This is probably sleep depravity talking but I think that this will be one of the better ones. Maybe even second best but the again sleep depravity.
This is OP because it stacks with Shudderwock, spawning out another pair of 8-8's will most likely force a Nerf for either of these cards. You might just go ahead and say "best Galakrond" since it's completely busted in the sense of its synergy, nothing else to say really.
Shudderwock will be gone from standard four months after DoD releases, and the new 35 card adventure in January will bring another meta change before that.
So I don't think they are going to change anything in the interaction between this two cards, and as a Wild Player I appreciate that.
