Man, I've lost count of the number of times I've thought OMG this card is OP this reveal season! Another insane card here. With such a high power level it's impossible to say which ones will be meta defining over just being effing good.
it's targeted so not gonna work well with shudderwork. it cost 5 with quest 7 that's way too much on top of that you need to overload last turn which means you have to spend a whole turn playing 5/5 that deals 10 dmg. not to even mention that quest shaman only runs 2 overload card and which you wanna play them way before turn 7.
wasp is just all around way better than this.
it would have been better if it was: if you have overloaded mana
