This is quite a stuffty idea, I don't mind if I get flamed.
Anyway, it goes as this.
There will be the four families, which is Hearts, Spades, Diamonds, and Clubs.
Each of them will have a different sort of attack, and they can be stacked together.
Pick up one you will only have twelve, since there are twelve cards in each family.
With this stacking, any combination is possible such as Diamond and Heart or Heart Diamond Clubs or all families at once.
With the stacking, your ammo should also increase, like if you got a deck of hearts, that would be twelve, you add another deck which makes it 24 and so on.
Decks should only be a max of 48.
I would also want a special to it, that if you right click, you lose all the cards, but it shoots all cards like a shotgun with a 50% chance of killing everything it hits.
The other 50% will just do little damage.
I think that's it for now, I'll just edit this post if any other ideas come to me.
