I'm truly wondering what the hell is going on with Warlock. Are we unwittingly testing ground for what are the strongest forms of mass board clear/control effects? Do they figure if they just put all their ideas in one class then they can see which are strong or not and how to translate that to the other classes?
The amount of things that affect the mass board state just keep growing, while not a single other class gets something that's relevant or competitive on this level.
This is a really strong card just unfortunately in probably the only class in the game that wouldn't jump on it, why the felt warlock needed this I don't know. Would have been amazing in other classes to help them out.
