Asellus, Mystic Conqueror

Eminence - During your upkeep, if Asellus is in your command zone, put a charm counter on target creature you don't control.

All other mystics you control have haste and first strike.

If Asellus is on the battlefield during you main phase, you gain control of all creatures that have charm counters, they are mystic in addition to their subtypes.

They took my life, I will take much more...
