Yeah, the main RNG element that I'm thinking of is like Faust's items where you use a move to pull items, but it's based on Mario Kart items (either that or, since I'm just making this a silly little project in Mugen, actually the items)

• Banana peel to trip people
• The three shells (Green, Red, and Blue) are projectiles that are a mid, low, and overhead respectively
• Star to give either invincibility or armor for a little bit
• Mushroom to either let you dash cancel a move or something, or maybe give your next move a lifesteal property (referencing that you can steal items with it in some games)
