I am late to the discussion. I will be voting this down for several resons. however I would like to propose a different concept. (but the Discord Discussion thread was locked)

What if unlocking a soulbound card was temporary... something like this:

What if it cost 10 vouchers to TEMPORARILY unlock the card to be listed for sale or rent. As soon as that card is sold. It becomes soulbound locked again but to the new owners account. If it's for renting. The unlock allows the card to be rented out to as many people that want to rent it for as long as the owner leaves it there. As soon as the owner takes if off rental the card is soulbound locked again and would require 10 more vouchers to be listed on the market again.

Card level would not matter. Same for all cards of all levels. Including gold foils.

So basically for 10 vouchers you get to trade that card once and then it locks again

Thoughts?
