What about prep + assassinate ? The mana cost also checks with a Shadowstepped Mecha’thun, and in this case, doing nothing for a turn is fine if you win in the next one, you just have to make sure you’re out of lethal and you win !
Keleseth will rotate before this, it might see play then, but there’s already a lot of better options for 2 mana anyway, but maybe we will see a demons based zoo in the future. Right now tho, this is just bad
