That Mirroir Magique deck looks CrAzY!
Ya, a friend of mine T8ed today with a modified build of it:
-3 Trop -2 Gemstone -1 Strip -2 Chant -1 Crucible -1 Zuran Orb -1 Kaleidostone -1 Triskelion -1 Top -1 Hurkyls
+1 Underground Sea +1 Volcanic Island +3 Scalding Tarn +1 Wheel of Fourtune +1 Ancient Grudge +1 Cunning Wish +1 Time Walk +1 Brainstorm +1 Inkwell +1 Thirst for Knowledge +1 Memory Jar
(more out than in because we went down to 60 cards)
I think Wheel and Jar definitely belong in the deck. We thought that Inkwell was a better finisher than Trike. Chants are good but got cut because we needed to up the Blue count to support Fow--11 is too low; our list has 15. The Cunning Wish was for an alternate kill condition in the board in case of Sadistic Sacrament, etc, but also ups the Blue count and gives you more ways to deal with hate.
The sideboard was different also--it included a couple of basics, artifact hate, Pyroblasts, and Leylines.
The deck looks like a pile of crap but is a blast to play and often manages to go quite broken: it is basically Steel City Vault with Mirror combo thrown in.
