Breaker functions the same way as Maw, but you'll be targeting pesky artifacts and enchantments with it instead of creatures
Moria Marauders ability reads: Whenever a Goblin or Orc you control deals combat damage to a player, exile the top card of your library
What's inside: NPCs divided into allies, villains, and wild cards (including an 8-year-old with a magical greatsword and Sissy Ontario, the urban druid)
All damage that would be dealt to you and other permanents you control is dealt to this creature instead
