@albarkhane said in Turbo Xerox and Monastery Mentor:
I am far from being an expert but from my little experience, when there are 2 dominating decks in a format the usual solution is a third deck that can predate on both of them.
This deck ought to be Oath of Druids, but I think the reason people call for Mentor's head is that a Mentor in play is often better than an active Oath. Mentor+3 Tokens+a grip probably beats Griselbrand handily.
Similarly, the big mana "i'm going to resolve Moat/other large spell" decks don't work because you don't actually out control and out-resource the TX deck. If they have an out at all, even if it's total jank like "Ultimate small jace, deck you"--they can stop everything you do and assemble it because they outdraw you so heavily. This isn't legacy, where the delver deck can be beaten with individual large spells, because you get to build resources while they try to cantrip to an answer--this is Vintage, where they'll build to 7 in hand versus your none in hand.
The closest to a good answer are the Outcomes decks (and, to an extent, the Gifts deck), because they are a big mana TX deck. They cash in some consistency in draw for "my cantrips draw 2-ifninity", but at heart, they are chaining draw spells until they find an answer/something that kills you, and have a passable shops matchup because they're playing a lot of mana.
The other angle to approach is Fish, but you lose so badly to Mentor->make 3 guys (not some insane sequence) and/or Walking Ballista that it's hard to justify the deck. You also have the problem of putting your TX opponent far down, and then them chaining spells into a balance and a full grip--things go wrong too easily.
Individual pilots have had success on other decks--but it's often something I chalk up to the pilot rather than the deck. Until anyone other than Josh Potucek picks up his Landstill deck and wins with it consistently, I'm going to say it's Josh being very good and the deck being at least playable, and not the deck being very good. Same story with @ChubbyRain .dec.
So yeah, people have tried, and so far, everyone has failed.
