Cultist Mystic

During your upkeep, put one Demonic counter on this card for each Demon creature you control.
You may remove four Demonic counters from this creature. If you do sacrifice one Cultist creature you control and create a 4/4 black and red Demon or four 1/1 black and red Lesser Demon creature tokens. Activate this ability only any time you could cast a sorcery.
