This is currently priced very close to burn value, and people are free to load up on vouchers at this price right now for this purpose. At this price bots will be able to flood the market with their cards, which will decrease the value of existing sets (which are already at lows) together with undermining the effects of cards burning and land to support prices. The release of these cards will fall in advance of the Rebellion sale ending which could also harm Rebellion pack sales.
The card surplus with many cards near burn value is seen as a problem to be fixed, at the expense of the community. Flooding the market with a vast number of these additional cards just compounds this issue. It's a no from me.
How is it priced very close to burn value if there is no burn value? "These unlocked reward cards will have no DEC burn value.”
