Gates of Hell

Gates of Hell enters play with four counters on it.
In the beginning of your upkeep remove a
counter from Gates of Hell.
When there are no counters on Gates of Hell sacrifice it: Destroy all creatures in play and deal
X damage to all players, where X is the numbers
of creatures destroyed this way.
"Beyond these Gates lies the realm of nightmares,
where darkness feasts on your very soul" - Zoltan, the Cursed Scholar.
