Understanding the Core Gameplay Mechanics
Evo Defense: Merge TD operates on an 8-column grid battlefield where your primary objective is to prevent enemy waves from reaching your King’s tower. What makes this game unique is its fusion of traditional tower defense with high-stakes RNG (Random Number Generation) mechanics similar to games like Random Dice.
The Summoning System
During battles, you’ll spend Silver Coins (earned by defeating enemies) to summon random heroes from your deck onto the battlefield. Each hero appears in the initial rows and immediately begins attacking approaching enemies. The key here is understanding that quantity often beats quality in the early game.
The Random Merge System
This is where Evo Defense truly shines and frustrates newcomers. When you merge two identical heroes (same type and level), you get a random hero from your deck of the next level. For example:
- Level 1 Archer + Level 1 Archer = Random Level 2 Hero
- Level 2 Mage + Level 2 Mage = Random Level 3 Hero
This randomness means you could merge two Ice Mages and end up with a Support unit you didn’t need. Understanding and managing this RNG is crucial for success.
The Enhancement System
The Enhance feature allows you to spend Silver Coins during a match to receive one of three random temporary buffs. These can range from attack speed increases to critical damage boosts and are essential for surviving difficult waves, especially boss encounters.
Mastering Merging Strategy: Don’t Brick Your Board
The single biggest mistake new players make is “Over-Merging” – immediately combining any two identical units they see. This approach will consistently lead to defeat. Here’s the proper merging strategy:
Fill The Board First Strategy
Step 1: Summon heroes until your board is completely full Step 2: Only merge when you absolutely run out of space Step 3: Always maintain board coverage to prevent enemy leaks
A full board of Level 1 units deals more consistent damage than a single Level 3 unit with slow attack speed. Eight Level 1 heroes attacking simultaneously provide better lane coverage and prevent enemies from slipping through.
Protect Your Core Units
Certain heroes are too valuable to risk losing through random merging:
- Ice Mage: Essential for crowd control with slowing/freezing effects
- Black Widow: Critical crowd control unit
- Kaka: Important support unit
Pro Strategy: Always maintain backup copies of your core CC units before considering merging them. If you merge two Ice Mages and get a random Warrior, you’ve just lost your primary crowd control and might lose the wave immediately.
Team Optimization & Class Bonds System
You cannot succeed by simply placing random high-damage units on the field. The Class Bond system is fundamental to building effective teams.
Understanding Class Bonds
Activate the Class Bond effect by including heroes from different classes in your team:
- Support: Healing and buffing abilities
- Mage: Magic damage and area effects
- Warrior: Tank units with high HP
- Archer: Ranged physical damage
- Controller: Crowd control specialists
When your team includes all five different classes, you gain a global +10% Damage Boost. In a game of numbers, this 10% advantage is massive and often determines victory or defeat.
Stage-Specific Optimization
Before starting any stage, check the stage information for class bonuses. Some stages provide massive buffs to specific classes (e.g., “+50% Mage Damage”). Always adjust your team composition to exploit these bonuses for easy victories.
Hero Tier List: Best Heroes for Progression
Based on extensive testing and community consensus, here’s the definitive hero tier list for 2026:
S-Tier Units (Game-Changers)
Annie: The quintessential summoner who floods the board with units that taunt, block, and distract enemies. She’s the cornerstone of the famous “Double Summoner” strategy that breaks through progression walls, especially from Chapter 50 onward.
Sea King: Annie’s perfect partner. While Annie provides quantity, Sea King provides quality with bulkier, ground-holding summons. Together, they create an impenetrable pressure cycle that keeps enemies away from your fort.
Ice Mage: Although less prominent in late-game builds, the Ice Mage is S-Tier for control. Its slowing and freezing effects are irreplaceable for managing enemy movement in early and mid-game waves.
A-Tier Units (Powerful & Versatile)
Cannon/Bomb Mage: The king of Area-of-Effect damage. Essential for clearing grouped enemies held in place by your summoners or Ice Mage.
Poison Archer: Master of consistent damage over time. Applies deadly toxins that chew through high-health enemies and bosses when raw burst damage isn’t enough.
Thunder Mage: Dominant in early to mid-game with strong chain damage and paralysis effects. Drops to A-Tier because some late-game bosses are completely immune to paralysis.
B-Tier Units (Situational)
Knight: Often a “trap” unit for beginners due to very short range. Usually doesn’t contribute meaningfully until enemies are already at your walls.
Athena: Pure support unit that boosts attack speed. Her buff is short and feels underwhelming unless you have multiple high-damage units to amplify.
C-Tier Units (Avoid When Possible)
Basic Archer and other early-game specialists that get quickly outclassed as you progress.
Complete Progression System Guide
Winning battles is only half the game. Long-term success requires strategic progression across multiple systems.
Hero Development
Level Up System: Use Hero EXP materials and Hero Shards to boost base stats. Focus your resources on higher rarity units (SR or SSR) as they scale better into the late game.
Recruitment System: Use Recruit Points (earned from Hero Recruitment) to unlock new heroes, get shards, and earn All Class EXP for faster leveling.
The King’s Talent Tree
Your King (avatar) has personal stats that significantly impact battle outcomes. Use Gold and Talent Stones to upgrade the Skill Tree.
Priority Upgrades:
- ATK (Attack): Increases overall damage output
- Crit Rate: Improves burst damage potential
- Crit DMG: Amplifies critical hit effectiveness
Gear System
Your King can equip 6 gear items, each providing specific stat bonuses:
- Boots: Movement and dodge stats
- Armor: Defense and health
- Weapon: Primary damage increase
- Ring: Critical stats
- Crown: Overall stat boost
- Necklace: Special abilities
- Belt: Additional defensive stats
Collect gear from stage completion rewards and enhance it using Gold Coins.
Totem System
Totems provide powerful aura effects for your entire team. You can embed totems into specific gear items to enhance both your King and team effectiveness. Obtain totems from:
- Totem Summon in the shop
- Special events
- Co-op battles
- Various game modes
Pro Tip: Always ensure your best totem is equipped before entering PvP or challenging content.
Daily Routine: Optimizing Your Resource Gathering
To maximize progression as a F2P or low-spender player, follow this daily routine:
| Game Mode | Objective | Key Rewards | Daily Priority |
|---|---|---|---|
| Replay Stage | Re-clear old stages with 100% HP | 3 Reward Chests (Hero Shards/Gold) | High |
| Arena (PvP) | Beat other players’ defenses | Ranking Points & Gems | Medium |
| Gold Mine | Daily resource dungeon | Massive Gold payout | High |
| Relic Hunt | Daily resource dungeon | Upgrade Materials | High |
| Co-Op Mode | Survive with a partner | Rare Gear & Diamonds | Very High |
Co-Op Mode Strategy
Co-Op Mode is the best place to farm high-quality gear. If you’re new, try to pair with a high-level friend or guildmate who can “carry” you to higher waves for better loot. This mode provides some of the best gear in the game that’s difficult to obtain elsewhere.
Stage Replay System
Each completed stage offers three reward chests that can only be claimed by completing specific tasks. The most common third chest requirement is completing the stage with 100% HP. This might be difficult initially, but after upgrading your heroes and King, you can replay stages to collect all three chests for additional resources like Gear, Upgrade Materials, and Diamonds.
Advanced Strategies and Pro Tips
The Double Summoner Strategy
This is the most powerful late-game strategy, especially effective from Chapter 50 onward:
- Build your team around Annie and Sea King
- Focus on summoning and merging these units
- Let their summoned units create an impenetrable wall
- This strategy often justifies breaking standard class-bond rules
Economic Management
Silver Coin Management: Don’t spend all your Silver Coins immediately on summoning. Save some for critical Enhancement moments during difficult waves, especially boss encounters.
Resource Prioritization: Focus on upgrading 2-3 main heroes rather than spreading resources thinly across many units. Quality over quantity applies to long-term hero development.
Common Mistakes to Avoid
- Over-merging early: Don’t merge units as soon as you see duplicates
- Ignoring stage bonuses: Always check for class-specific bonuses before starting
- Neglecting King upgrades: Your King’s progression is as important as hero upgrades
- Wasting Enhancement buffs: Save Enhancements for critical moments, not every wave
- Breaking Class Bonds unnecessarily: Only break the 5-class bonus for specific strategies like Double Summoner

Frequently Asked Questions
What is the best starting strategy in Evo Defense: Merge TD?
The best strategy is to fill your board with Level 1 units before considering any merges. Having 8 units attacking simultaneously provides better lane coverage and prevents enemy leaks early in the game. Only merge when you run out of board space or have backup units ready.
How do I get more SSR Heroes?
You can obtain SSR heroes through:
- Summoning using Diamonds or Golden Keys
- Farming Hero Shards by replaying Campaign stages
- Opening the 3 victory chests daily from completed stages
- Participating in special events
What does the “Enhance” button do?
The Enhance feature spends Silver Coins during a match to give you a choice of three random temporary buffs. These can include attack speed increases, critical damage boosts, or other temporary power-ups. It’s recommended to use Enhance during later waves when summoning becomes too expensive or during boss encounters.
Why did my hero change when I merged it?
This is the core mechanic of Evo Defense: Merge TD. Merging is completely random. When you combine two identical units, the result is a random unit from your deck of the next level. It does not maintain the same hero type, which is why you must be strategic about when and what you merge.
Which heroes should I avoid merging first?
Avoid merging core crowd control heroes like Ice Mage, Black Widow, or Kaka early on. These units are essential for managing enemy movement and preventing leaks. Always maintain backup copies before considering merging these critical units.
What is Class Bond in Evo Defense: Merge TD?
Class Bond is a bonus effect activated by including heroes from different classes (Support, Mage, Warrior, Archer, Controller) in your team composition. Activating this bond provides a global +10% damage boost to all your units, which is significant for winning difficult battles.
How often should I upgrade my King vs. Heroes?
Focus on upgrading your King’s core stats (ATK and Crit Rate) early, as these benefit your entire team. Simultaneously, focus on leveling 2-3 main heroes rather than spreading resources thin. Balance your upgrades based on what’s holding you back – if you’re lacking damage, upgrade King/ATK; if specific heroes are weak, upgrade them.
Conclusion
Evo Defense: Merge TD is a deep strategic game that rewards careful planning and adaptability. The key to success lies in understanding the RNG mechanics, managing your economy wisely, and building teams that synergize well together.
Remember these golden rules:
- Fill your board before merging
- Protect your core crowd control units
- Always activate Class Bonds when possible
- Focus on a few main heroes rather than spreading resources thin
- Use the daily game modes consistently for steady progression
With this comprehensive guide, you now have all the knowledge needed to progress efficiently through Evo Defense: Merge TD. The game’s depth comes from mastering the balance between randomness and strategy, and with these tips, you’ll be well-equipped to handle whatever challenges come your way.
