With a bug. New draft pick doesn't check if the spells you joined with are removed or not. Also, in addition, Riot didn't actually removed any spell from game, they only removed you ability to pick it.
Basically, if you have an account which you played with any removed spell on it in your last game, you can join a draft pick and still have it.
This has been "fixed" since though, and all removed spells are now actually removed. You can still get into game with it, but you are simply going to play with 1 spell.
