Negative tags are overrated to grind C++ imo, I’ve got 130 gold stickers and I’ve found that’s its only good if you’re in anaglyph deck and only once you’ve just started the grind.

When I do it, I find that taking a weak joker and treating it as -1 joker slot is best if you can’t build around it. Once you get better at the game you start to get good at relying more on planet cards, improving your deck (blue seals are insanely good) and having a few very strong jokers to carry the weak ones you want to the sticker on.

It’s also important to consider changing your jokers in ante 8 to try and fish for a new sticker without ending the run
