Donatello, Gadget Master

Sneak {1}{U} (You may cast this spell for {1}{U} if you also return an unblocked attacker you control to hand during the declare blockers step. He enters tapped and attacking.)
Whenever Donatello deals combat damage to a player, create a token that's a copy of target artifact you control.

Infiltration {1U}
À chaque fois que Donatello inflige des blessures de combat à un joueur, créez un jeton qui est une copie d'un artefact ciblé que vous contrôlez.
