Captain Premal

At the beginning of combat on your turn, choose
target nonland permanent you control. Until end of
turn, it becomes a Vehicle artifact with base power
and toughness each equal to its mana value, and it
gains crew 2 and "Crash Land — Whenever this
Vehicle deals damage, roll a six-sided die. If the
result is equal to this Vehicle's mana value, sacrifice
this Vehicle, then it deals that much damage to any
target."
