This is Reality, an Azorius deck using Monastery Mentor as our Win Condition. The opponent is playing a deck that aims to abuse the power of Shigeki along with powerful cards to wear down opposing decks.
My friend, we are still working on the deck, but here is the list we have so far. Deck List: Deck 6 Plains 5 Island 3 Negate 2 Dissipate 3 Impulse 3 Monastery Mentor 1 Field of Ruin 2 Devious Cover-Up 3 Ambitious Farmhand 2 The Celestus 4 Deserted Beach 2 Witness the Future 2 Farewell 2 The Wandering Emperor 4 Raffine's Tower 4 Idyllic Beachfront 3 Lay Down Arms 3 Union of the Third Path 4 Invasion of Gobakhan 2 Sunfall
My friend, you can try Bounce, targeted removal, or something to help the Mentor stay alive or get him back from the grave. Out of those, I think I'd go with removals.
