The best pile I can come up with Mirror requires a 2nd Draw (probably Meditate #2 or Leyline/Planar Void/your opponent being kind enough to Crypt/Relic you post-Meditate), but it would be something like this:

Meditate, Rain of Filth, Lion's Eye Diamond, Sensei's Divining Top, Mirror of Fate

This requires 3UB from 5 lands and plays out like this:

Doomsday for these cards and pass. Untap, draw Meditate. Meditate into your four cards. Play Rain of Filth (1 land available). Tap the land for for mana and then sac your 5 lands (6 mana available). Play SDT. Play LED. Play Mirror of fate and activate for:

Meditate, Petal, LED, LED, win condition of choice/IGG, irrelevant cards/win condition

You then break LED to SDT into Meditate and cast it. Where you go through the motions of playing accel into SDT which can get you IGG if you need to inflate storm (and there are no forces to worry about) or just something like Tendrils. You could also put another SDT there and top into top, play top #2, pay 1 and rearrange to put Tendrils on Top, and win from there.

If you can make another 4 mana, you can afford to put Chant/Duress in there somewhere (from more lands off rain of filth, or maybe Dark Rit or LED). There is a lot of design space using rain of filth and double Meditate, but drawing Mirror of Fate would be fucking terrible. God forbid that ever happens. It would probably love me more than IGG, so I'll never run it, but if you feel the need for ultra-complex pass the turn piles, I guess it fits the bill.

Edit: You can cheat mana on this pile using LED if you stack the pile differently. You can put SDT, Meditate, Rain of Filth, LED, Mirror. The difference is that you draw and play SDT and then pay for Meditate with LED. That means you might be to do something like use Dark Ritual instead of Rain of Filth to pay for Mirror. That would take 4B. This lets you do it with Dark Ritual in hand and LED, and two lands in play when you pass the turn.

For anyone that cares, I'll be playing this list +/- like 2-3 cards for awhile:

4 Polluted Delta
4 Flooded Strand
2 Island
1 Plains
1 Swamp
1 Tundra
1 Scrubland
1 Underground Sea
1 Tropical Island
1 Bayou
1 Lotus Petal
4 Lion's Eye Diamond
4 Dark Ritual
1 Rain of Filth
4 Sensei's Divining Top
4 Brainstorm
4 Ponder
4 Orim's Chant
4 Silence
1 Wipe Away
1 Krosan Grip
4 Mystical Tutor
4 Doomsday
1 Meditate
1 Ill-Gotten Gains
1 Tendrils of Agony

I'm currently playing with the 4th Ponder, the 7th and 8th chant effects, and the Rain of Filth. In these slots, I've been testing, amongst other things:

1 Enlightened Tutor
1 Isochron Scepter
1-2 Krosan Grip
1 Wipe Away
1 Rushing River
1 Engineered Explosives
1-2 Cabal Ritual
1-2 Infernal Tutor

I'm not entirely sure on Isochron's Scepter's usefulness. Obviously you want the random scepter chant locks in game 1 and then board it out. I'm just not sure that you'd ever ETutor for this over SDT or LED. Chantwalks with 8 chants in the upkeep seem to be good enough to buy time vs aggro. If they can't play spells, they don't have creatures, and thus can't kill you. Cabal Rits and/or Infernal Tutors increase the goldfish speed. Rushing River is just another way to handle stuff like Chalice @ 1. EE is the same that is also pretty adept at killing CB or stopping multiple Goyfs to buy time. ETutor has two main targets, the LED and SDT that I mentioned already. It's seeming to be the best addition of the lot, although I'll be testing the rest in depth.

I'm probably going to play Cabal Rits, Infernal Tutors, Extirpate, Helm, Grapeshot, Serenity, more KGrips, any extra chant effects I don't maindeck, and ETruth + Rushing River in the sb.

I would have gone for the last option which was IGG into Chant/Duress/Meditate and slow-played it after Duressing his bomb. We play more cantrips and take less mana to win if he has to go for Infernal Tutor.

As for the Duress situation, it's unconditionally Ad Nauseam. He doesn't have Threshold (or anything close) so Infernal Tutor is worthless as it will take at least 7 mana to make it useful (he's short 4).

The pass the turn pile (which no longer works well due to the rules) is:

Meditate
LED
LED
Burning Wish
Burning Wish

You Meditate into the four cards, Burning Wish breaking LEDs for R and B to get IGG, play IGG floating BR to get back 2x LED and the 2nd Burning Wish. Repeat the cycle into Burning Wish into Tendrils for exactly 20 lifeloss (9 storm + tendrils). This takes 3UR on the turn after Doomsday. It's more difficult to pull off if you can't cheat mana with LED into Meditate.

To make this work with the new rules, you need an IGG in the sb to wish for and then it makes 18 lifeloss (might be good enough for a pass the turn pile). If you put a Wish in the sb, you can then Wish for Wish which makes a lethal Tendrils.
