so the rule to the Phoenix dial is if a member of the dial is KO'ed then you turn the dial 5 turns. Grundy however cheats death with his ability and tokens. so if you "kill" Grundy and he comes back. do i still get to turn the dial?

You should quote the powers in question.

He is not KO'd unless he has no tokens, so no you would not turn the dial. (except for his official KO)

The FF Grundy however is KO'd each time. His shard would return to the resource after his first KO. Whether or not he would still be considered "assigned" to the Phoenix Force is up for debate right now.

I guess the reverse is then true, those using the phoenix force won't get to do a single click and turn the dial because of his power unless it's the final KO.
