Well, I am not familiar with splinterlands. Like you said, the ECR being similar to RC: if the ECR snd DEC are kind of built on the same system the powerup could work. You know, like how Hive and HP are.
It could work with something like an escrow system where you "pull out" ECR from your account and put in the marketplace.
This is idea is really an epiphany. The escrow thingy would at least hold the DEC and ECR and not like one would kind of dissappear into oblivion. It sounds more like a transaction now.
