Alyro, Distinguished Hedonist

Whenever you draw one or more cards, you
may discard a card. If you do, put a +1/+1 counter on Alyro.
When Alyro dies, for each +1/+1 counter it
had on it, exile up to one other card from
your graveyard. You may play cards exiled
this way until your next turn's end step.
