Doctor Zseimel, Data Miner

At the beginning of your end step, you may exile a card from your graveyard. If you do, if there are at least 4 cards in any other graveyard that share the type with the exiled card, put a +1/+1 counter on Doctor Zseimel, Data Miner and surveil 2, then you may search your library for an artifact with mana value less or equal to the number of +1/+1 counters on Doctor Zseimel, Data Miner and put it into the battlefield. If you do, shuffle afterwards.
