See, this is difficult because there’s so many??? Let’s start off with winjimstiel though. There’s like… 21 fics on ao3. The first winjimstiel fic was posted in January of 2016, I believe. I have hope it’ll pick up speed but it’s happening so slowly *cries*

There are only 21 winjimstiel fics on ao3? That’s a freaking tragedy. We need to get that number up higher because holy wow does this ship have potential. 

I wanna see more of it but I especially like the idea of partner swapping with this ship, whether it be accidental or on purpose. Like, maybe Sam and Cas have to go do a thing and Cas gets sick so Jimmy shows up in his place and Sam’s really worried it’ll mess with Cas’s reputation but everyone loves Jimmy (because of course they would). And maybe Dean has to nurse Cas back to health and poor Cas pukes on him or something. 

OOOOH! OH! Maybe they’re all rival spies and Cas and Jimmy swap to get information from Sam and Dean. Kinda like a Mr. and Mrs. Smith au!
