When Basalt Ravager enters, it deals X damage to any target, where X is the greatest number of creatures you control that have a creature type in common.
Each instant and sorcery spell you cast costs {1} less to cast for each creature it targets. Heroic — Whenever you cast a spell that targets Battlefield Thaumaturge, Battlefield Thaumaturge gains hexproof until end of turn.
Whenever you cast a spell that's both red and white, Battlegate Mimic has base power and toughness 4/2 until end of turn and gains first strike until end of turn.
Mimics don't need perfect disguises. They need only the perfect victims: the naive, the young, or the poor of sight.
