Goblin Bomb

Enchantment

At the beginning of your upkeep, you may flip a coin. If you win the flip, put a fuse counter on Goblin Bomb. If you lose the flip, remove a fuse counter from Goblin Bomb.

Remove five fuse counters from Goblin Bomb and sacrifice it: It deals 20 damage to target player or planeswalker.

Goblin Bomb is on the reserved list, which means WOTC has self-imposed restrictions from making functional reprints of this card.
