@garbageaggro I'd love to try and figure it out, but at the moment, I honestly don't think there's enough varied cards in White that can successfully nuke token-based strategies. The main issue being that Mentor runs white, and has access to Swords to Plowshares and can put me off plays while SIMULTANEOUSLY significantly adding to power/toughness on the board, which I generally don't want to block.
I've made some edits to the deck, and I'm getting happier with what's been happening.
I'm pretty certain that Spirit Guides are the way to go for this deck. Getting turn 1 plays is massive, and Spirit Guides allow me to retain the Stony Silence/Null Rod plan and still let me accel. The downside is that my hand gets emptied far quicker, and I don't have the ability to refill... at all.
Enlightened Tutor has been absolutely a game changer. If I make a good enough metagame call, I can plop a Tutor and search for the most effective strategy against the deck they're playing. A frighteningly large number of cards (for a creature deck) can be searched up. This is incentivizing adding in Thorns, although I'm not quite sure.
Tried Black Vise for a few days, and it made a huge difference in about a half of the matches I played. It kept people from using Library, and it hit at least two times in games where I played it. A few games were won off the back of that card alone. The issue is that it isn't a prison card and those slots needed to go somewhere else.
With the accel now available, I added 2x Eidolon of Rhetoric and kept one Ethersworn Canonist. Eidolon actually helps more against Mentor because Mentor gets triggered off of Moxen, which can still be spammed with a Canonist. Canonist is also a 2/2, and will likely get attacked into, whereas Eidolon is a 1/4 and that matters way more than it should...
SB: Windborn Muse needs more accel than I currently have to be effective, but Ghostly Prison got so much better after including Enlightened Tutors, as is Ratchet Bomb, Aegis of the Gods, and Suppression Field.
I cut 1 Grand Abolisher, 2 Judge's Familiar, 1 Path/Swords, 1 Plains, 1 Vryn Wingmare and 2 Leonin Arbiter to make room.
New thoughts are adding one Wingmare back, as Flying is actually a big deal against Mentor. Might try one maindeck Ghostly Prison to be on the safe side game 1 against Mentor.
New Thalia just dropped today on MTGO (i think) and I can't wait to test it. Might even try a version with Winter Orb for the good old fashioned soft lock.
It's not over, but it's definitely an uphill battle, one that I don't think will get better with slight tweaks. The games have been absolutely dreadful.
