Fire Navy Trebuchet (TLA 100)

Artifact Creature — Wall • Mana cost: {2}{B} • Avatar: The Last Airbender • Uncommon

Defender, reach
Whenever you attack, create a 2/1 colorless Construct artifact creature token with flying named Ballistic Boulder that's tapped and attacking. Sacrifice that token at the beginning of the next end step.

The trebuchets would be destructive enough even without the fire.
