Whenever a creature you control becomes blocked, you may return it to its owner’s hand.
Whenever one or more creatures you control deal combat damage to a player, draw a card.
Grazilaxx's first ability triggers before combat damage is dealt. If you choose to return the creature to your hand, it won't deal or receive combat damage.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
