Vorapede

Trample, hexproof, vigilance, undying
Leyline 10 (If this card is in your opening hand, you may begin the game with it exiled with 10 time counters on it. If you do, it gains suspend.)
As long as Vorapede is exiled, creatures you own that aren't on the battlefield gain Genepool and Biotheurgy. (Each +1/+1 counter you remove from creatures you control while casting them pays for {1}. They enter the battlefield with a +1/+1 counter on them for each creature type they share with creatures you control.)
