This guide breaks down exactly why every single viable deck must feature a dedicated anti-air package and how to construct a flawless aerial defense.
The Danger from Above
The Balloon will simply float over your defending ground troops, drop a single bomb, and instantly delete a massive chunk of your tower's health.

If you drop an 8-elixir Golem and the opponent plays a 5-elixir Minion Horde directly on top of it, the Golem will die before it even crosses the river if you do not have a spell or anti-air support ready.
If you play your Musketeer and they kill it with a Fireball, you are 100% defenseless against their incoming Balloon.Flying anti-air units (like Mega Minion) are safer because they avoid ground melee.If you place a Wizard and a Musketeer right next to each other, a single Poison spell will kill both, leaving the skies wide open. Choosing Your Air Guards
The 'Air Assassin' role (Mega Minion, Phoenix, Minions) involves playing flying melee units that fly out to directly intercept the enemy threat in the sky.

Choosing the correct combination of these three roles ensures that you are never caught without an answer when the opponent takes flight.
