Lord Izlar, the Forgiven

Vigilance
If a Non-token, Non-land permanent on the battlefield is sent to the graveyard, reveal the top
card of your deck, if it is an artifact your opponent returns a card from their graveyard to the deck,
if a creature search your deck for an artifact equal
to half its cost RD-U add it to your hand
"Some forget there past, others run from it, I killed mine".
