Personally, Im looking forward to adding Soulless Jailer to my Heliod, Sun-Crowned cEDH deck in order to have yet another weapon against Underworld Breach and some other similar strategies
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
With affinity for artifact creatures, it will be very rare to have to spend mana to cast it outside of the three esper colors, given the number of ways there are in Commander to mass create tokens
Foil, extended art, and borderless versions of popular cards, like Gemstone Caverns (LTC-364) or Herald of Eternal Dawn (FDN-423), tend to rise in value
