If you want a build that can literally delete enemy teams before the fight even starts, this is the one. The Full Undead + Fire hybrid is currently dominating because it stacks multiple insanely strong traits together — and when combined properly, it becomes very hard to beat.
This guide breaks down everything: troops, traits, positioning, upgrades, and how to actually play it in matches.
Merge Tactics Meta Builds Season 7 (April 2026) – Full Undead Comp
This strategy revolves around one simple concept:
You activate Full Undead to massively weaken enemies at the start, then use Baby Dragon + Wizard to finish everything instantly with splash damage and speed buffs.
The result is a comp that:
- Cuts enemy HP before the fight starts
- Deals massive AoE damage immediately
- Counters melee-heavy teams
- Scales extremely well with upgrades
All Troops in Merge Tactics Meta Builds Season 7
Here are the exact units required for the full build.
Undead Core (Main Engine)
These are mandatory because they activate the strongest trait in the comp.
• Skeleton King
• Giant Skeleton
• Skeleton Dragon
• Witch
These four together activate Full Undead.
Fire + Support Units
These add damage, buffs, and extra traits.
• Baby Dragon
• Wizard
Together they activate Fire, Dragon, and Hinder bonuses.
Traits Activated in This Build
Full Undead Trait
This trait activates when you use Skeleton King, Witch, Giant Skeleton, and Skeleton Dragon together. At maximum level, it reduces half of the health of multiple enemy troops before combat even begins.
This is what makes the build extremely powerful because enemies start the fight already weakened.
Fire Trait
This trait activates when Baby Dragon and Wizard are used together. It increases overall damage output and improves the impact of splash attacks.
It works perfectly with the Undead trait because enemies are already low on health.
Dragon Trait
This trait activates when Baby Dragon and Skeleton Dragon are used together. It reduces damage taken from melee units and increases damage dealt to them.
Since many teams rely on melee troops, this gives your team a strong advantage.
Hinder Trait
This trait activates when Wizard and Witch are used together. It increases the effectiveness of splash damage and helps control enemies by slowing them.
This makes Wizard attacks much more deadly.
Merge Tactics Meta Builds Troops Guide
Baby Dragon
The Baby Dragon acts as the most important unit in this build. It increases the strength of nearby troops by boosting their attack speed and movement speed. It has a very large attack range, which allows it to hit enemies from a safe distance. Its first attack deals extremely high damage, often hitting multiple enemies at once. Because of how valuable it is, keeping this unit alive is very important for winning fights.
Wizard
The Wizard serves as the main damage dealer in the team. It deals powerful splash damage that can hit multiple enemies at the same time. When combined with the Hinder trait, its attacks become even stronger. It is capable of clearing weakened enemies very quickly after the Undead trait activates.
Skeleton King
The Skeleton King acts as a frontline tank. It absorbs damage and protects your backline units. It also plays a key role in activating the Undead trait, which is essential for the build to function.
Giant Skeleton
The Giant Skeleton provides area damage and frontline pressure. When it gets defeated, it deals heavy damage to enemies nearby. This helps weaken enemy groups even further.
Witch
The Witch mainly supports the team by helping activate important traits. It also deals ranged damage and contributes to the Hinder trait synergy.
Skeleton Dragon
The Skeleton Dragon adds extra ranged damage and helps activate the Dragon trait. It also has good survivability compared to other ranged units.
Best Positioning Strategy
Proper positioning is very important for this build.
You should place the Baby Dragon in the center or slightly behind your team. All other troops should be positioned around it so they can receive its stat bonuses.
Frontline units like Giant Skeleton and Skeleton King should be placed at the front to protect your damage dealers.
The Wizard should stay behind the tanks but still close enough to benefit from Baby Dragon buffs.
Upgrade Priority Order
For best results, upgrade your troops in this order:
First upgrade Baby Dragon because it is the core of the build. After that, focus on upgrading Wizard to increase damage output. Next, upgrade Giant Skeleton to strengthen your frontline. Then upgrade Skeleton King, followed by Witch and Skeleton Dragon.
Getting a three-star Baby Dragon is usually enough to secure victories.
Early Game Strategy
In the early game, focus on collecting Undead units first. Try not to spend too much elixir on upgrades at this stage. Saving resources helps you secure Baby Dragon when it appears.
The build becomes much stronger once you activate the Full Undead trait.
Mid Game Strategy
During the mid game, you should begin upgrading Baby Dragon and Wizard. Start building a strong frontline using Giant Skeleton and Skeleton King. Make sure your formation is centered around Baby Dragon.
This is the stage where the build starts dominating fights.
Late Game Strategy
In the late game, your goal is to get three-star upgrades for your main units. Keep your formation tight around Baby Dragon and replace any weak units if needed.
At this point, most enemy teams will be defeated very quickly.
