However, ignoring the vertical space—the 'Z-axis' of the arena—is a fatal flaw that will immediately stall your progression on the competitive ladder.

Flying units operate under a completely different set of physical rules than ground units.
Why the Skies Matter
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.

Furthermore, aerial swarms (like the Minion Horde or Bats) can completely shred an unsupported ground tank in seconds.
It hides underground to avoid predictive spells and deals massive damage to Balloons and Lava Hounds.Use Tornado to pull flying units.Small spells are critical for aerial defense. Choosing Your Air Guards
The 'Ranged Sniper' role (Musketeer, Electro Wizard, Flying Machine) provides consistent, high-range DPS that can hit air units while remaining safely behind your Princess tower.

If you are playing a heavy Beatdown deck, you must also include 'Splash Anti-Air' (Baby Dragon, Electro Dragon, Executioner).
The DangerYour StrategyThe Lava Hound (Massive flying tank)Ignore it initially; focus all anti-air on the support troops behind it, then clear the 'pups' when it popsThe Inferno Dragon (Escalating beam damage)Use an Electro Wizard or Zap spell to constantly stun it and reset its damage beam to zero Respecting the Z-Axis
Test your new decks specifically against heavy air combinations before taking them to the ranked ladder.

When the shadow of a Balloon falls across your tower, you must be ready.
