At its absolute most basic, foundational level, every single competitive arena battler relies on a very simple childhood game.

This guide will break down the combat triangle and show you how to exploit it to guarantee positive elixir trades.
Swarm, Splash, Single-Target
For example, a massively expensive P.E.K.K.A (Single-Target) will absolutely destroy a Wizard (Splash) in a one-on-one fight.

If you blindly play a swarm without baiting out their splash damage first, you are throwing your elixir away.
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.Sacrificing a cheap card to get to your primary defense is acceptable. Breaking the Triangle
Once you understand the basic Rock-Paper-Scissors rules, you can begin to actively subvert them using ‘Bait’ strategies.

You are no longer playing the cards on the screen; you are playing the player behind the screen.
