There are uncounterable spells too...
Anyway, I realized that I had not built a Visificationnessity deck yet, so I threw one together, and it is SO bad. I mean seriously, it is so suboptimal. It has two Tradewinds, but not enough creatures to utilize them properly. It has only one Boomerang, because my others were in my FinishingSchool and ArcticCircus decks, and it also has no FoW for the same reason. It's basically random countermagic with random bounce and some good creatures, and the Vises...
However, I found out the perfect recipe for Visificationnessity. 4x Black Vise and 56x other cards. It really doesn't matter what's in a Visificationnessity decklist, as your opponent will never see it. You will watch him drop a first turn Vise, then, desperately lay down your Treetop Village. Then he'll play ANOTHER VISE. So you'll know that you need a way to empty this hand and pass up Wall of Blossoms for Llanowar Elves, only to have it Boomeranged. Then, oh, that's it. The fact that your opponent only has one Boomerang and is actually using Memory Lapse matters not.
Vise is so broken.
