i recomend adding an option for SoV. i just tested it out and i got a 22|28 golem with vampire... gg
edit: dont cast SoW on it or it wont heal you
double edit: not so great actually, i just tested it again and i got a golem with voodoo... not so great
i just posted a deck built around getting vampire
http://elementscommunity.org/forum/index.php/topic,42233.new.html#newit's true you need 3 SoVs and sometimes you have to be patient for that...you also have to be patient waiting for 2 SoWs cuz immortality is pretty much a must. still, dropping a huge vampire golem (ideally it's airborne and Sofreedom-boosted) even a few turns later can stop new dmg in its tracks and quickly finish a game.
also there was some suggestion above that novas could clog the hand and slow down SoB drawing, but i don't think that's a big deal. a bigger issue is the opponent's hand being too full to use all the SoBs you'd want to...i run 6 novas just fine. black holes haven't been a huge issue either, even when they hit normally it's after the main golem drop and/or i have another nova as necessary.
SoW+reflect shields, turtle shield, GP+voodoo are bigger threats. healing rushes like mitosis/empathic bond/life or fractal/vamps/dark can compete, but dang does SoI pack some efficient, speedy punch with a decent draw...
awkward draws are probably the biggest problem. don't get an early SoFree and the rest are useless. have to make your golem before you've got 2 SoWs and a) your ass is hanging in the air and b) future SoWs are also useless. too many SoIs reduces the golem's attack, don't get one and you're a shard farm. get a 3rd SoW while waiting for something else, and you'll get lobotomize instead of vampire (which is worse and you can't pay for it mostly), so you gotta draw to 8 and discard the extra SoW.
SoBs help mitigate draw issues to an extent but with only 6 quanta cards there's less overlap between you having room in your hand and your opponent having room in his hand than you'd like...ultimately this deck requires a lot of patience and some luck but it hits often enough with a big immortal (flying) vampire and when it does it crushes a lot of things.
