Favorite deck is definitely Anaglyph, no question. The feeling of hitting several negative tags is just far too fun for me, but obviously it gives you much more flexibility for skipping to really turn around something you're behind on (like economy as you mentioned). I also like Ghost deck a lot given the free polychrome, and the unique ability to get spectral cards in the shop.

I think people hating on Black deck is pretty much the norm, so I'll say another one that bothers me is Nebula deck. It's not even that it's particularly super hard as much as it is that I can't stand only having one consumable until maybe Crystal Ball shows up as a voucher. I want to collect tarots to utilize in the shop before opening a tarot pack, so I have to hold one fewer card. I want to gamble on High Priestess and Emperor sometimes (or maybe just pump numbers up for Constellation or Fortune Teller), but they are way less useful. Sometimes I'll just take one absent-mindedly and then realize, that's right, I'm on dumb Nebula deck and only get one card roll. Sometimes I want to hold onto a copy of the fool and utilize a blue seal, or maybe two blue seals, and I can't do that either. Ante 1 telescope voucher is not worth this price.

As for Erratic deck, I was expecting a lot more than what it actually is because I guess I didn't consider probability properly. Most of the time when I check the deck for any given seed I get a somewhat even suit spread with all cards somewhere between like 2-6 in quantity. I already reset for an actually useful small blind skip tag, no way I'm also tacking on significantly more for a much more rare interesting Erratic deck.
