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.
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

Because flying units avoid so many standard defensive interactions, they require highly specialized, immediate answers.
It hides underground to avoid predictive spells and deals massive damage to Balloons and Lava Hounds.Use Tornado to pull flying units.Zap or Snowball can instantly kill Bats or severely injure Minions, giving your tower time to finish them off.
Structuring Your Defense
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.
This is because your massive ground tank will inevitably attract massive enemy aerial swarms, and you need a single unit capable of clearing the entire sky with splash damage.
Enemy Aerial ThreatHow to Defend ItThe 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
Total Coverage
You must respect the skies and build your defenses with complete vertical coverage in mind.
When the shadow of a Balloon falls across your tower, you must be ready.
