Ideas: Curses and Synergies

[Ponygood11]

So, a lot of people already know about the synergy between the Endless sticker and the Madness Joker, right? Madness tries to destroy an Endless Joker, fails, but still increases its xMult?

It might be cool to have Jokers that synergize with the other stickers, too. Let's say, for example, there was a Joker that has +Mult or xMult for every dollar you have below 0-- something you can't normally do, since it's only possible with the Credit Card or the Tooth Blind, but then when your jokers have the Rental Sticker, you can way more easily get the benefit of that Joker. Or maybe you have a Joker that creates a new Joker every time a Joker is disabled, which is an incredibly niche power that you can only access from the Crimson Heart Blind, but then you add the possibility of the Perishable Sticker, and suddenly the really niche Joker becomes a whole lot more consistent. (Actually, maybe there can be more Jokers that also disable other Jokers? That's a thought.)

More Stickers would be really cool, if they each had their own negative effects that were generally harmful but had niche synergies with certain Joker cards, or even new Joker cards. Maybe Stickers shouldn't be locked to higher Stakes, but instead accessible through other means mid-run?

And speaking of negative effects, another idea could be: Curse Vouchers. These Vouchers give you money when you take them, but have an unambiguously negative effect with no benefit, like, "X Sticker can appear on Jokers," "-1 Hand Size," "Playing card effects disabled," That sort of thing. If you're desperate for the money, or you have a Joker that would synergize with the negative effect, you may be tempted to take it, but otherwise... they're probably avoidable? Like, maybe they appear at the same time as the normal Vouchers? Or maybe they don't have to be Vouchers, but something else that you can access in some way?

Honestly, I really don't know where you could add additional systems to this game, it's incredibly tightly-designed as it is, but if it's possible, it really would be cool to have these sorts of expanded curse/negatives in the game. Taking a lot of inspiration from Slay the Spire, of course, how it has curse cards you can receive in certain circumstances that take up a spot in your deck, and most of the time you want to avoid or get rid of them, but then there's some situations where you can actually get some use out of them.

Notably Sacrificial Dagger has to actually destroy the joker to get the benefit. Madness is the only card that can still increase its xMult even when the other effects fail to occur.
