I see instant kill combo's via cremation;
but I guess that's fine as it requires 3 cards from different elements.
Can the player playing mind control choose a target in case of a nymph/oty/parasite?
also, what happens in case of a gravity nymph?
I think, unless combo'd with some specific cards,
the 'it is treated as a friendly creature for the rest of the turn' is a negative effect:
it means that the creature removes 1 frozen/delayed counter (on attack),
it means that the creature grows from SoP...
when exactly does 'the rest of the turn' end?
at the drawphase of the opponent?
just before the opponent attacks?
at your next drawphase?
