Building a MMBN inspired game, and I'm curious to get your thoughts on deck construction limitations.
In the MMBN games, your folders have limits around which cards can be used. Each game was slightly different, but there were limits on how many copies of a single chip could be added and how many mega/giga class chips could be added.
I'm curious to know if you like those limits, or how you would improve them given the chance. One thing I've been toying around with is the concept of "total memory" or cost in a folder/deck. Instead of limiting the amount of cards that can be used based on rarity, cards would have a cost to equip and a deck would have a total capacity that all 30 cards would need to fit into. There would then be ways within the game to either increase this deck cost cap, or reduce the cost of certain battle cards (combining duplicates, for example, could reduce the cost to equip them).
I'm trying to find that nice, fine line between allowing the players to have fun with their rare and powerful cards, but not making the game too piss easy by allowing them to spam giga class attacks all willy nilly.
