Choosing the correct combination of spells is arguably the most critical deck-building decision you will make, as they dictate your ability to finish games and secure positive trades.
Conversely, missing a heavy spell is the single fastest way to lose a match, instantly putting you at a massive elixir disadvantage.
The Heavy Hitters: Nuking the Arena
These spells—such as Fireball, Poison, Rocket, and Lightning—serve two critical functions: destroying expensive defensive structures and providing guaranteed tower damage in overtime.
Poison provides identical total damage but spreads it out over several seconds, making it the absolute hard-counter to continuous Spawner buildings or Graveyard spells.
Lightning requires three distinct targets to achieve maximum value.Poison creates a zone of area denial.Only cast it when the enemy unit is stationary, or lead your target perfectly.
The Rotational Spells
Complementing your heavy nuke, your deck must feature at least one (often two) 'small' spells, costing 2 or 3 elixir.
Arrows, costing 3 elixir, sit in the middle; they lack special utility effects (like stun or knockback) but offer a massive radius and enough damage to kill tougher swarms like Minions and Archers.

The Perfect Synergy
A well-balanced deck almost always features exactly two spells: one heavy/medium for structure removal, and one small for swarm control.
Choose your spells to perfectly cover the weaknesses of your primary win condition.
