I think the deck is funny but you have no actual win condition against Emrakul/ Kozilek/ Ulamog. So in my opinion it is necessary to include 2-3
Surgical Extraction. I do not think you need that much
Ojutai's Command. And I would cut at least one Snapcaster. You need more generic counters such as
Spell Snare/
Mana Leak/
Condescend. And you sghould definitely cut the Idyllic Tutors. The
Judge's familiar looks out out place too. What you definitely need is a second win option. maybe you should build the deck as a hard control deck with the combo. But relying on the combo without generic support or a second win condition might not be the best.
