Custom games need to be more customizeable

Like, when I make a custom game I want to have fun and do crazy stuff, especially when I want to 1v1 someone who picks an entirely different champion I didn't ask to duel

Custom games should have these features:

• Custom amount of starting gold
• Restricted items
• Restricted champions
• The ability to manipulate stats
• Basically everything in practice tool but unchangeable when the game actually starts
• When there's a small team size, the time you have to wait for surrendering decreases
• Literally every single gamemode that ever existed
