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

In this digital version, the triangle consists of Swarms, Area-of-Effect (Splash) Damage, and High Single-Target Damage.
The Core Mechanics
However, that same P.E.K.K.A will be killed instantly by a cheap Skeleton Army (Swarm) because it can only attack one tiny skeleton at a time.

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?"
Only launch a Swarm attack when you know their Splash unit is not in their hand.Air units add a secondary layer to the triangle.Sometimes, playing into a counter is necessary to fix your hand. Breaking the Triangle
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.
