Crackling Doom deals 2 damage to each opponent. Each opponent sacrifices a creature with the greatest power among creatures that player controls.

Enchant land you control

Enchanted land is a 3/3 red Spirit creature with haste. It's still a land.

If enchanted land would be destroyed, instead sacrifice Crackling Emergence and that land gains indestructible until end of turn.

Flash

When Crackling Spellslinger enters the battlefield, if you cast it, the next instant or sorcery spell you cast this turn has storm. (When you cast that spell, copy it for each spell cast before it this turn. You may choose new targets for the copies.)

At the beginning of each opponent's upkeep, Rackling deals X damage to that player, where X is 3 minus the number of cards in their hand.
