how many items you can have
you could make a menu before the match starts allowing you to pick your item and recommend an item amount and it will give you the normal amount if not recommended but if you do recommend it will have higher odds of you having more ex: you only have 8 snowballs but you can recommend 10 or 12 and if you do not get the higher amount you will get the default amount
which this could lead to some insane combos allowing you to maybe 360 snowball combo someone
