Very interesting. The dec to unlock, will it be burned? or locked up? I like the idea of it as a DEC sink. Maybe pay the fee to unlock it but once it's been moved to another account it potentially be rebound and the cycle gets repeated. I think that might eliminate the flood of each card in the market and allow for those that want to collect them or max out each card an opportunity to do so.
