Lurr, King of Predation

Whenever you cast a creature spell, you may put a +1/+1 counter on that creature. Creatures you control with +1/+1 counters have Menace and can't block.
Whenever a creature you control dies, draw a card for each counter on that creature.
Elders speak of "The Law of the Jungle." Absurd. I've seen the jungle, and there is no law there.
