While the standard ranked ladder requires you to master only a single, perfectly optimized deck of eight cards, Clan Wars are an entirely different beast.
This article analyzes the absolute best cards to level up specifically for Clan Wars and how to distribute them across your four war decks.
The Holy Grail: Small Spells and Swarm Clear
The most immediate and brutal bottleneck you will face when building four unique decks is the severe lack of reliable small spells.

The true strength of a Clan War player is determined by the depth and level of their spell portfolio, not the level of their primary tank.
- Never waste a versatile card in a highly specialized deck.
- Put it in the deck that absolutely requires grouping units together (like with an Executioner).
- Check the specific war rules for the week.
Versatile Support Units and Substitutions
Beyond spells, the other major hurdle is replacing key support units, particularly anti-air defenders.
Cards that provide multiple functions—like the Electro Wizard, who provides anti-air DPS AND a spawn stun effect—are incredibly valuable in Clan Wars.
| Deck Concept | The Rule |
|---|---|
| Deck 1: The 'Main' Ladder Deck | Use your absolute best, highest-level cards here to guarantee at least one flawless victory for your clan |
| Deck 4: The 'Leftover' Deck | Usually a bizarre, off-meta creation (like a double-spawner deck); rely on confusing the opponent rather than raw stats |
Depth Over Peak
A player with one maxed-out deck and thirty level 1 cards is a liability to their guild in a serious Clan War.
Broaden your horizons, master the substitutions, and bring glory to your banner.
