Description

Problematic Volcano (CMB2-60) is a World Enchantment from the Mystery Booster Playtest Cards 2021 set that forces older Worlds to be put into graveyards when it enters. When it enters the battlefield it deals 4 damage to any target, and then each player assigns their creatures to the left or right of the volcano, establishing sides for that card. Creatures on one side cannot block creatures on the other side, but the card only affects blocker declaration and other game actions and targeting can still cross sides.
