Endless, Increasing Tickling

When you planeswalk to this plane, put a tickle
counter on it. Whenever a creature with power greater than the number of tickle counters on it
enters the battlefield, put a tickle counter on this
plane.
Creatures get -X/-0, where X is the number of
tickle counters on this plane.
Chaos: Put 2 tickle counters on this plane.
I think someone needs a tickle!
