Inky, Blinky, Pinky, Clyde

Flying
Whenever Inky, Blinky, Pink, Clyde dies return it
to the battlefield with an additional -1/-1 counter
on it until it would have four. As long as it would
enter the battlefield with less than four -1/-1
counters, create a 1/1 white spirit creature token
with flying for each -1/-1 counter it enters with.
Once Inky, Blinky, Pinky, Clyde would enter with
four -1/-1 counters, exile it instead.
