Wisps deck given new life by
Crack the Earth and
Eremot's Machinations. Insane value.
Ark of Sol is also a solid addition, and it can be triggered by either Shadowlands Guide[card] (harder) or the cultist token created by
Crack the Earth (quite easy). All in all, a really consistent and fun deck.
Grodov's Burden is really interesting in the deck, but I think you probably pick
Xenan Temple over it 99% of the time, so it might be better to just replace it with a board wipe (Eremot's Design maybe).
Silences really hurt the deck, so don't play into a turn 3
Valkyrie Enforcer. In fact, try to play a wisp and immediately give it killer and trade, so that they cannot silence it on board (void silence is still very possible and crippling).
I'm really curious if the deck (or a variation) can be viable in throne (I suck way too much in that mode to even try), so if you do try it out, please tell me how it goes.
