You guys are crazy if you think banning Cori or Mice will shake up the meta. You still have swiftspear, FOMO, Boltwave, Boros charm... Red will never ever go away, the backbone is too strong. I'm betting on boros package. FOMO and Lightning will result in turn 4 kills which go through any blocker with ease. Fomo>Lightning>4x damage on boros charm. Beyond that FF has some nice cards that provide gas and haste for red, Brynhildr is the next cutter contender and a card I'd spec on if cutter eats a ban. 1R 2/1 that draws a card and hastes two creatures is nuts

...
Should I buy 1000 copies of Brynhildr?
