Is the energy on Glutton Cauldron affected by Warden of Argos?
No. The Warden's energy option makes players discard tokens from their reserve, and energy on the Glutton Cauldron is not in the reserve, so it is unaffected (the Enchanted Kingdom rulebook lists the Glutton Cauldron among the exceptions). The Warden's other option makes players discard a Power card from their hand, so it does not touch cards in play either.
