Room

Mecânica MTG

Room is a new enchantment type. Room cards are similar to split cards, but with a major fundamental difference: they're permanent cards. Each Room card has two halves, called "doors." Pick one half to cast, and that door unlocks on the battlefield, giving you access to that half's abilities. Pay mana to unlock the other door later and get access to everything! Abilities that trigger "when you unlock this door" will trigger either way.
