Thoughts

So this is weird. 60-12 on the core this week. Everyone placed with the same main. That is, the list discoverN has been running. The sideboard is the only difference and there's not much there.

discoverN is the only one on Library of Alexandria. Two copies of Tasigur, the Golden Fang sneak in. They seem to be an alternative to The Tabernacle at Pendrell Vale. Diem4x and bennybo both forego this extra card for Bazaar, instead choosing to have a second Opposition Agent.

With the amount of BUG and Shops seemingly being played right now, I think discoverN's list is mostly right. I do wonder if we want to start packing a fifth piece of hate for Shops. Either Hurkyl's Recall or Energy Flux would be the best candidate. However, Hurkyl's Recall is difficult to cast in the spot we want it - against multiple hate pieces, and Energy Flux is quite pricy at three mana.
Perhaps a second Fatal Push would work. This works double duty against Phyrexian Revoker from Shops and the many creatures out of BUG. A second Opposition Agent would be a good call if the mirror is on the rise again.
