Urborg Mindleech

Shroud
Cannot block and can't be blocked.
When Urborg Mindleech deals combat damage
to an opponent, each player reveals the top card
of their library. If the revealed card is a
permanent with a converted mana cost of 2 or
less, that player may put it into play. Otherwise,
they may pay an amount of life equal to that cost
to put it into their hand.
