When players first begin their journey in an arena battler, they almost exclusively focus on the ground war.
They entirely bypass the river, they are immune to powerful ground-control spells like The Log and Earthquake, and they cannot be distracted by standard ground-melee troops.
Why the Skies Matter
If a player sends a Balloon at the bridge, and your only anti-air card is a 3-elixir Minion squad buried at the bottom of your deck, you have already lost the tower.
Because flying units avoid so many standard defensive interactions, they require highly specialized, immediate answers.
The Tesla is arguably the best anti-air building.Use Tornado to pull flying units.Small spells are critical for aerial defense.
Structuring Your Defense
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.
If you are playing a heavy Beatdown deck, you must also include 'Splash Anti-Air' (Baby Dragon, Electro Dragon, Executioner).

Look Up
Test your new decks specifically against heavy air combinations before taking them to the ranked ladder.
