The entire combat system is just a highly complex, beautifully animated game of Rock, Paper, Scissors.

Learning exactly how these three categories interact is the first step toward building a viable deck and predicting enemy movements.
The Core Mechanics
The rules of the arena are simple: Swarms overwhelm Single-Target units; Splash Damage obliterates Swarms; and Single-Target units destroy Splash Damage.

Every time you place a card on the battlefield, you must ask yourself: "Which part of the triangle am I playing, and what does the opponent have to counter it?"
A deck with only swarms will be destroyed by a single splash unit.Know instantly that a Valkyrie is the perfect response to a Goblin Gang.A well-timed Zap can save your Single-Target unit from a Swarm. Advanced Baiting and Archetypes
Bait decks are designed entirely around overloading one specific side of the triangle to exhaust the opponent's counters.

You send your first swarm to force them to use their spell; the second they do, you unleash your primary swarm attack safely.
PlaystyleThe LogicSwarm OverloadIntentionally breaks the triangle by having more swarm threats than the opponent has splash countersPerfect DefenseAdheres strictly to the triangle, ensuring they always have the exact perfect counter ready in hand at all times The Evolution of Balance
If Splash units become too strong, nobody will play Swarms, and Single-Target units will dominate the ladder.

Know your counters, track their spells, and execute your trades perfectly.
