I'm maxed out on resources and cards and I can't spend resources on upgrades until my current upgrades are finished, can't give it to the alliance hall since that's maxed out and can't sell N cards since it would exceed my maximum resources... I mean, I could grind a high level campaign map to damage my units and spend it on healing but that's a huge waste of time. Any faster way?
