i had a sort of random thought as i was going through runs, so i just wanted to put it out here
what if rental costs were based on joker rarity? because currently, rental jokers can be a big drain on economy early on, but it seems unbalanced in the way that rental common/uncommon jokers are more punishing to pick up with it due to the normal cost of them being instantly/almost instantly surpassed by their rental cost, which i think is outside the spirit of the sticker
as an example, a rental rare will cost you 10 money after 3 rounds, which is also say the same cost as a blueprint. however, common jokers will cost that same amount for normally much less value or potential (situationally)
with this idea, i was thinking that common jokers would cost $2 at the end of the round, uncommons would remain costing $3, and rares are bumped up to $4. this allows you to get short term value out of rental common rentals without it being as much of a huge detriment earlygame, while the rares (often blueprint/brainstorm, with a few others) are even more costly to pick up as rentals and would balance it out a little
