One possibility is to cast Apocalypse, a card that gets rid of everything, including your hand, leaving you only with Barren Glory, but that needs to be done on your upkeep, so there are options like Leyline of Anticipation or Emergence Zone to give these spells flash

That Bonder's Ornament will be surprisingly useful when you find yourself needing an answer in a couple of turns

Sacrifice it at the beginning of the next end step if it has mana value 3 or less

Late-game, when everyone is looking to close out the game, then it seems fine

You can do this to draw a card after your mana is set or in response to the massive recursion and graveyard (ab)use at the Commander table
