Menace
Whenever Grime Gorger attacks, exile up to one card of each card type from defending player’s graveyard. Put a +1/+1 counter on Grime Gorger for each card exiled this way.
The card types that might appear in a player's graveyard are artifact, battle, creature, enchantment, instant, kindred, land, planeswalker, and sorcery. Supertypes (such as legendary and basic) and subtypes (such as Human and Equipment) are not card types.
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.
