Heart of Bogardan

Enchantment

Cumulative upkeep

When a player doesn't pay Heart of Bogardan's cumulative upkeep, Heart of Bogardan deals X damage to target player or planeswalker and each creature that player or that planeswalker's controller controls, where X is twice the number of age counters on Heart of Bogardan minus 2.

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