Maddoct, the Mad

Creatures with no +1/+1 counters on them you control have persist.
Whenever a creature you control with a -1/-1
counter on it dies, return that card to the battlefield under your control at the beginning of
the next end step with a +1/+1 counter.
At the beginning of each upkeep, increase the
number of counters on each permanent you
control by 1.
