While troops and buildings form the physical foundation of your deck, spells represent your direct, unblockable influence over the battlefield.
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
If your opponent perfectly defends your ground pushes all game, your heavy spell is your only remaining win condition in sudden death.
The Fireball is the most versatile medium spell, offering instant burst damage capable of severely crippling support units like Musketeers and Wizards.
Patience is key.Do not guess the math.If they are playing 'Spell Bait', do not use your heavy spell on their weak swarms.
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.
