I am not super confident I understand how the back side of these cards are supposed to be used (click the image to see). The image makes me suspect that it records increases to the cost of keys, and it is automatically attached to every Grabber Jammer, Murmook, and Jammer Pack that is played. But having a card that is always attached to another card doesn't feel like something that is inherently helpful. Lash of Broken Dreams and Iron Obelisk would have the amount of cards behind them change so often, that it feels overly fiddly.
Is my assessment right, or am I missing something obvious?
