Attracting new players with something that costs over a thousand dollars.... I can't see that how that would be an easy thing. Toss out a freeby or two here and there would get you more attention. Ask anyone in advertising/marketing. (no, you don't give away the whole dang show...but one or two?? sure!)
Would I say to do that with the Wakas? Nope. Burn all of them that haven't sold on the Splinterlands platform. You save their worth/value for what did sell, and you eat the loss until tax season and claim it on your expenses for the year.
Next promo is when you apply what you learned on that last round
