GenoSans, Determined Sans

When GenoSans enters exile, destroy all other Sans cards on the field. You gain life equal to half their combined power.
If GenoSans leaves exile, you may Reset, or Continue. (Reset: Destroy all permanents exept for GenoSans. Continue: Place GenoSans back into exile)
GenoSans can only activate his abilities in exile.
