Where did you see his abilities?
Nevermind, found it. Seems pretty meh...
Dang, he really sucks!
I have Sorin and cannot find a build for him. Any PW that has any mana ramp abilities will smash your face in. This isn't a problem if black/white had that ability too. Basically I've only won games against other black decks.
I'm probably doing something wrong though....
It might be more geared for a zombie deck than for a lifegain deck:
he produces 7 with white and black and at least 10 with any cascade using white and black.
From under the floorboard is 7 mana while diregraf colossus, prized amalgaman and fleshbag marauder are 10 mana.
Plus damaging relentless dead is not that bad.
It just feels that his first two abilities cost a little too much, do they at least count as separate instances of life gain for each damage or gem destroyed?
