Real simple: This is the card that makes Black White Tokens as good as it is right now. Star City Games just sold out at $1.00. I think they'll re-up their supply and relist it at 2 bucks. Ebay usually lags behind SCG, but considering that its a must-play 4-of in the deck, there's no way they don't start selling it for more than a measly buck. It's not going to pass $2.50 or so, but might as well get them while the getting's good.
Target: $2.00 per card, June 1st
