The problem is that DCE trades/sells far better than Wailord ex does. It doesn't matter if a card is theoretically worth a certain amount if it doesn't sell for that. Trust me, I've done my research. To keep my collection growing, I generally only do trades if I feel I can easily turn around and trade/sell the stuff for more than I gave away for it.
For that reason, I have to pass. Sorry.
Wow. So you're flat-out saying that if you don't get the better end of the stick you don't trade.
