Woah that is one of the best sorare cards you couldve gotten! Lord Vanaken is part of sorare lore.

The new minting system is a step in the right direction and I like the whole clues functionality.

I managed to mint a Kerim Mrabti which I sold for $10. I am doing your exact plan - sell (slowly which means, undercutting daily as new cards are minted) any in season reward cards earn and stack that ETH and exit.

I will continue to playing with my classics till the platform decides to call it a day or my classic card players have retired (I have had a few already this season retired so those NFTs are now useless)
