Fill the bag. Empty the bag. Whatever strikes your fancy. Anybody running either and/or mechanics will love this. Especially in multiplayers where the player count tends to churn through tokens fast, "sanding off" tokens and preventing the really big play, like a Hallow.
In my opinion one of the most interesting places for this is Carolyn Fern, who can run both Hallow and Rite of Equilibrium, although you might want to do this with some curse usage or management in the team.
