Enchantment
Cumulative upkeep {2} (At the beginning of your upkeep, put an age counter on ~this~, then sacrifice it unless you pay its upkeep cost for each age counter on it.)
When a player doesn't pay ~this~'s cumulative upkeep, ~this~ 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 ~this~ minus 2.
