I always disliked uncounterable instant kill mechanics, and no - I don't consider highrolling your Mutanus to be a viable counter.
Of course this is the perspective of someone who likes long control vs. control games, where managing your resources and value cards is the name of the game. Knowing that you will now also play against the Xyrella-clock that will get you eventually might just ruin my favorite Warrior vs. Priest games.
At least it won't be viable in Wild, as you can't step into *any* game without 1/4 of your cards being pure disruption at this point.
