Use a dragon with ground as its primary element if you are going against Crossfire dragon.

Crossfire's elements are fire, ground and lightning. Fire and ground attacks will deal Weak damage against ground primaries. Lightning will have "No Effect" on those having ground as it's primary element which is cool. So, Crossfire will have to stick to its lame old physical attacks which only deals a minimal amount of damage.

Dragons having ground as its primary are like Tropical, alpine, Flaming Rock and Star.
