Absorptive Caudate

Calling
Whenever another creature enters the battlefield,
you may move a +1/+1 counter from Absorptive
Caudate onto it.

Whenever a creature you control with a +1/+1
counter on it becomes the target of a spell or
ability you don't control, counter that spell or
ability unless its controller pays {x}, where X is
the number of +1/+1 counters on that creature.
