Siege-Bred Drake

Haste, first strike
When Siege-Bred Drake enters the battlefield, it
deals X damage to target creature or player.
If target creature is destroyed this way, its
controller loses life equal to its power.
"These drakes have no qualms with flying head first
into castle walls, landing in the middle of a heated
choke point, or toppling siege engines."
-Zima, drake tamer
