No flips for you!
Oh, like hitpoints! And AC points! And Death Saves!That's my take on most forms of metacurrency as well. They are simply tools to enable players to temporarily gain some 'non-character action declaration' narrative control. The purpose seems so transparent and yet it's often acted like there's no difference in metacurrency mechanics for that purpose and for ones that allow players to declare X happens in combat (whose reason for existence is to balance martial combat abilities around more than %chance to proc mechanics - example battlemaster superiority dice).
ETA: the opposition to metacurrency always seems so much special pleading to me.
