I've been hopping back and forth between a dozen decks (including Shops and Jeskai, but other stuff too). I felt good about my Kess deck at champs, but it's broken on MTGO and the meta seems to be shifting in a way that might make it worse. I try to keep a variety up for streaming, but I'm also just trying to get a handle on what beats what.
I am playing paradoxical oath or a 4c Kess deck that is very hard to tweak for the Ohio meta, but I think could be quite good in the online meta, if the cards worked correctly there.
I am playing paradoxical oath because I love combo and oath in the same deck is the best plan i have found for beating shops with combo.
I have also had aggro shops built to test against, because I find that having what you want to test against with you is helpful.
UWR Stoneblade. I maintain it's the best of the Boat/Dig/Gush/Planeswalker decks against Shops, since Stoneforge is such a brutal clean-up hitter against them (no, really--their deck becomes Ravager or Bust), but you do suffer some against Oath.
But realistically, the answer is "no". You look at my deck and you go huh, that's the Jeskai deck.
I'm playing Sun Titan Oath because it is fun. I believe you need to win the turn you Oath and this deck does that about 75% of the time. I was winning with it but I over-corrected for Shops and lost to some blue decks. That will not happen again.
Dredge. It is just the most powerful thing I can be doing, has a 50/50 or better match up against most decks in the format (modified by sideboard construction), it has an absurdly strong game 1 against basically everyone, and it's actually super fun and intricate.
Baral 2cc Combo with manamorphose, gifts and regrowth. The deck is called "Almost good".
Grixis Thieves: It's really important to play timetwister. Pulling the Mind Twist + Draw 14 wins not just the game, but the match in most circumstances because the opponent starts g2/3 with a tilt token in play. Also, I have wanted daretti II to be good since it was printed.
(in short: play night's whisper. card is good.)
I'm stuck on U/W/r Bomberman in the current shops meta. Also, 4color Landstill with Deathrite shaman but without Leovold. I'm just more comfortable facing shops with these two and I know I have game vs everyone else.
Burning Oath, DarkPetition Storm, ANT, and Doomsday are always fun decks for me in random metagames/ events, where I just wanna end the games quick.
I'm playing Oath, because at this point, I think I'm better at playing it that other people are at preparing for it. I think you need actual sideboard commitment to really hurt it, and many decklists just don't really commit enough to that. Also, I think it gives the best combination of punch and surprise... basically, I think it's the most underplayed deck when compared to sheer "brokenness" (it that term even means anything), and I think you therefore get at least a good game against almost any deck in the format, while picking up a high amount of cheap wins on broken draws and lopsided matchups.
I'm working on a slaver list with 3 Welders and 2 Darettis because it's 2005 in my head and Welder+Gifts is incredibly powerful and fun. It's rough because vintage has perhaps never been more hostile to our favorite little artificer; Misstep, Ballista, Revoker, and the power of graveyard hate today compared to a decade ago all work against him.
In response, I sometimes run 1-2 Cavern of Souls to dodge Misstep. In addition, Daretti sidesteps Revoker on welder and guarantees at least one weld before eating it to a Ballista. Grave-hate is rough, but Tezzeret cares not for it.
I play Gifts when I don't want an uphill battle vs the entire meta.
