Yeah, I see a lot of decks that brag about SoG, and I'll admit the one hasn't been THAT helpful. Maybe if I had more. But it's possible the nerf has made them less relevant.
SoSas... haven't considered it. It seems like a bad way to deal with a bad situation: you're taking lots of damage and you're waiting for your quanta to come in so you can do something about it... so you do a lot of damage and throw out all your quanta. When would you use that shard to your advantage? Would it be often enough to be worthwhile?
You don't seem to understand the effect of 'Sosa.' Link
http://elementsthegame.wikia.com/wiki/Shard_of_Sacrifice_%28Upgraded%29Its three effects are:
- Drain all quarta except
- Decrease your HP by 32
- Swap any damage with healing for the next two turns, stalkable
This means that if you have more than 32 hp, you are invincible for the next two turns (poison, creature, weapon, spell), and if lucky, get a lot more than 32 hp. Currently, Sosa is being extensively used in many decks, including neurotoxin, mono death, etc.
Sorry, but I forgot about the 'drain all quarta except
, so it would not work in this situation, as your deck is primarily
.
