All random mode that changes your champ on respawn?
Seriously, like, change your champ on respawn, you get refunded all spent gold, don't get a champ swap on an execute, buy a ward slot item that lets you keep your champ on death (100 gold), and 100 gold divining rod that points you towards a role you'd rather play as (Marksman rod, fighter rod, etc)
mix it with urf for all i care, this just sounds like fun
