Arbalest Engineers

Creature — Human Artificer — {1}{R}{G}

When this creature enters, choose one — • This creature deals 1 damage to any target. • Put a +1/+1 counter on target creature. It gains trample and haste until end of turn. • Create a tapped Powerstone token. (It's an artifact with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.")
