Can a player exhaust a rune for no reason (without using the energy) in order to ready it again with Mana Flow and effectively gain an extra rune?

Question

Accepted Answer

Ruling: Yes, you can exhaust a rune for no reason. Runes have the text "Exhaust - Add 1 energy" which can be activated without needing to use the energy generated, allowing you to exhaust it and then ready it again with Mana Flow.

Nuances:

The ability is written as "Exhaust" not "Reaction," so it can be activated at any time without requiring a trigger
