Good luck on the licence, I don't have enough knowledge on those to really get into them. I used to have vouchers in the liquidity pool but have too bad of an experience with impermanent loss to really want to take the risk.

For as far as the cards goes, I guess it all depends on the time horizon. in the long run I'm crushing it on my collection, compared to what was the top I got crushed. I kind of gave up on the fact that Cards will go up in value, if they remain somewhat stable and give some returns from playing and rentals I'm already happy.
