When Arbalest Engineers etners the battlefield, choose one —

• Arbalest Engineers deals 1 damage to any target.

• Put a +1/+1 on target creature. It gains trample and haste until end of turn.

• Create a taped Powerstone token. (It's an artifact with “{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.”)
