Hey, I feel you. I too have stopped playing Splinterlands. I simply don't like the direction the game is developing into. So I am selling my cards too. The collection is worth a meager $336 since I already sold more valuable/gold cards.

I would be interested in a free market with the ability to list "all" or "filtered all" your cards with one click. I would even pay a fee for such a commoditiy :)
