So have Western RPGs, namely the Diablo franchise. But, Diablo has padding to RNG that was added to the game progressively. Now, you can soulbind an item to have the ability to roll 1 stat on it, which I would love to see with cards (basically allow us to reroll one stat on a each card for some kind of FARMABLE fee, no stupid crystal rerolls, goodbye poison resistance). This feature was added about one year after the launch of diablo 3. Then about 2 years after launch we got the expansion and Kadala, a merchant who distributes (special) gear by giving her rift shards (sounds familiar right?). Now, fastforward another 2 years (I think might have eben a year) and we got the Cube added to the game. It had 4 main functions, but the one we need in this game is: put in mats plus original item, pops out a rerolled item (I'm looking at you my 3 grade 1 rank 6 cards I have, literally all my rank 6's I've been able to obtain have rolled rank 1). The cube also functioned a heck ton like the current card system: you could imbue legendary items (with special affix's that changed skills) to the the cube and use an affix from your a weapon, armor piece, and accessory (hence why I say its like the current card system), but in diablo once you burned a stat affix into the cube you could apply it or switch it any time in town.

How would I adapt this model into Future Fight? Well, give us stat rerolls on cards (1 stat reroll=5 two star cards). Allow us to have an item (like the cube) where we can put specific stat bonuses in by sacrificing comics to it (I'm thinking infinity gems?). Also, let us use this interface to completely reroll a comic cover. Make the materials steep, like 100 bios (to reroll an item in diablo, its 40 exotic salvaged mats, or roughly 4 hours of farming per reroll on a top 1000 leaderboards level toon). That would make rerolls achievable, but you have to work/devote resources to it. There, that is what we call "kid glove" RNG. There is still RNG, but we can spend resources to correct it somewhat (albeit, by RNG, but still better than being stuck with a bad roll).
