+1: Put a lifelink and vigilance counter on target creature with "this creature is now colorless in addition to their creature types."
-3: All lands on the battlefield instead produce colorless mana until the end of your next turn. During this time they produce double the mana value.
-7: The match enters a "pause phase." You then choose another game from the outside world to finish the match against a target opponent.
