Phir Sé's Portal

This card enters the battlefield with a charge
counter on it. At the beginning of your end step,
double the number of charge counters on it.
Remove all charge counters from this card,
sacrifice it: This card deals X damage to target
creature where X is the number of counters
removed this way.
Phir Se's portal opened beneath Behemoth's feet,
aimed upward, and a plume of light speared into the
sky, consuming Behemoth, covering him.
