Thanks you for your advice. Blood Moon seems like fun, too, but I'd rather be blue based. Standstill looks fine. Therefore I'd make the following exchanges:
3x Standstill for 3x Preordain
3x Tundra + 4x Mishra's Factory + 2x Islands for 7x Islands + 1x Plains + 1x Tundra
3x Wasteland for 2x Back to Basics + 1x Thing in the Ice
1x Crucible of Worlds for 1x Jace, Vryns Prodigy
2x Stony Silence for 2x Null Rod
Maybe take out Mystical Tutor or Merchant Scroll for another Swords.
Maybe add Narset Transcendent, I really like her.

I love long games, but my biggest threat is the time on magic online. Guess I need to train a bit more 🙂

Thanks guys and best regards,

@brass-man thanks Brassy! The Enlightened Toolbox deck is coming along, though likely Brendan will make some big changes now with the Mentor boogeyman restricted, maybe I'll ask him to post his new list when he gets the chance 🙂

Congratulations to @neo_altoid for taking Seat of the Synod Mentor to a Top 8 finish in a recent Vintage Challenge.

@bazaarofbaghdad

Fascinating list. Part of me really wants to try to port it over to Legacy.

In the actual meta (see the last vintage challenge) it could make sense to maindeck Containment Priests. Dredge and Oath are stronger than ever and the Ambush Viper mode of the Priests make them even usefull in almost any matchup but Storm and Paradoxical.

@PeAcH thank you!! I'm looking for something like these, not a fan of the card art ones that I've seen, i'll check them out!

I have seen most Mentor lists run 4-6 hate pieces. IMHO 2 each of Preist, Cage, and RIP, since those all also hit Oath (RIP if its Sun Titan Oath for example), have been the best combination. It also depends on if your list runs the singleton strip, or wastelands as well as those are hate on bazaar.

@PeAcH you can start an account on MTGGoldfish for free and that allows you to post your results there. It's simple cut and paste and I'd consider it a favor if you all did this. 🙂 let me know if I can help.

during your games, what did you name on phyrexian revoker? i mean at this point, I'm wondering if running more null rod is not the way to go...
Also, I'm quite surprised not seeing any eye of ugin in the different lists

Wow even a drain friendly metagame like LCV has 6 decks out of 8 running Gush in the top 8... This is clearly going to be a problem going forward.

Restricted since 1966.

@gkraigher I've played some games with Wire and some games without ... I've had trouble figuring out the right ratio of threats-to-lock pieces in the Robots deck. I don't feel comfortable yet saying one build is better than another
