4Clash Royale card guide
Inferno Dragon is a flying troop whose beam deals more damage the longer it locks onto the same target. It's one of the best answers to tanks in the game.
Use Inferno Dragon against tanks like Golem, Giant, Mega Knight or Lava Hound; its beam melts them over time. On offense, Mega Knight and Miner decks use it as support to clear the opposing tank and defense.
Cards that deal with it efficiently:

This card has an evolution. The evolution is active in your deck’s 1st (Evolution) or 3rd (Wild) slot. The Evolution slot unlocks at Arena 3, the Wild slot at Arena 10.
ElixirDeck automatically takes your unlocked evolutions and heroes into account: build your decks.
