Does pricing makes sense? The rare card is more expensive than the legendary card O.o (in vouchers)
I would also add that the price of the cards in vouchers seems like a little expensive. Almost is not worth using vouchers for this.
also, why include DECB? decb is already burned theres no need to burn it again. Seems like a waste.
Vouchers are valued at 50 DEC each, which is roughly equal to the current market price. For some players that may be worth it and some not. I believe that many players have excess Vouchers that they would prefer to spend on a promotion like this than sell on the market, but if not, then that just means more DEC will be burned, which is fine.
Also, the purpose of DEC-B was that it can be used in place of DEC any time DEC tokens will be burned. Players took a large opportunity cost converting DEC to non-transferrable DEC-B when the token needed support during the bear market, and it's important that there are opportunities to take advantage of that.
