A random idea. How about removing the poison and change the ability to:
: Doom.
Doom tank and target creature suffers 15 damage after 3 turns.
So it'll be a kamikaze weapon, which spread Deathness till it's dies. The upped could be OP though, but I think not.
That would be viable, but if I go with that, I should both drop the poison and the voodoo. Maybe that would be the right choice as skyironsword also mentioned earlier, but I'm a bit hesitant on dropping both. But if you both agree, I will change the card to the new ability what Zergva said. However, Chapuz also mentioned that it can go pretty OP if exploited with BB and PU, so that is also kept in mind.
So what do you think?
I don't really see the quanta optimalised version of the tank-BB-PU deck. It's need too much wait from your opponent, no CC-s for 3 turns, no attack or no PC for the Dim. shield spam (which needs more
quanta. And this not that type of trio, what can be changed to SN based. And still an RT can ruin everything. Although my idea was a random suggestion, so if it'll become popularly favorited, it can, but if not, just forget it
