Cluny, the Scourge

Ward {2}
If a creature an opponent controls would die, exile it instead.
At the beginning of each end step, create X 1/1 black Rat creature tokens with "This creature gets +1/+1 for each other Rat you control," where X is
the number of creatures that were exiled under your opponents' control this turn.
