Snake Oil is great! And there's nothing like it, but it's GC so that's good.
Aren't the 13s usually chocolate based? You may want to check out other chocolate and cocoa recs, here's a giant and delicious thread of recs:

Of Cheshire Cat, is it the citrus that you like? You may want to try some of the other citrus scents, like:
Aelopile
Embalming Fluid *super zingy and bright!
Phantasm
Xiuhtecuhtli
Manhattan *really a great scent!
Mag Mell *love this!
Cairo *This one is so great!
Shanghai

Thanks so much -- these are great recs! The 13s ARE pretty chocolate based! I love those two most for their complexity (the orange label one is like, a spicy chocolate orange -- like eating a chocolate orange in a spicy incensed room, and the april one is like if you took wildflowers and poured white chocolate all over them with something a little spicy in it as well to give it a little heft), Cheshire Cat I like because I know it's meant to smell like citrus, but it actually smells like fruitcake to me?? Something about those glaceed cherries and warm, eggy bread, and booze. I don't know why because I don't see a lot of people saying it smells like that to them, but there's something not classically citrus that comes out real strong on me, and I love it!
One thing that I've noticed about many of the chocolate blends is that they feel pretty strictly gourmand? and while I love a gourmand, I tend to like it with a little spicy stink thrown in, too. I'll certainly have a looksee, though. Thank you so much for taking the time to recommend!!
