Edge of the Void

Whenever a creature an opponent controls dies
you may pay {u/b}, if you do you may return a
creature card from your graveyard to your hand.
Whenever an enchantment is put into any
graveyard from anywhere draw a card, if it was
put there from a library you may draw two cards
instead, if you do, discard a card.
It is said that a planeswalker who enters the void at
the heart of the Astral plane can use it to travel
anywhere .... or anywhen.
