I think they're cutting and pasting somehow, but I'm on Android and haven't figured out how they do it yet...unless it's an Iphone only thing..
I think if you go into "My Trades" and got to an accepted trade or declined or whatever, you'll see a star rating beneath the trade...I think that's what you've been given...I got a really low star rating a while back, my first and only bad one and I don't know why, the trade was just dupe swaps with a regular trade partner...but it looks like they gave me a 0 if that's possible ? (The stars are all hollow ?)
Yeah, while it's a pretty good idea to spur trading (or desperation really) I'd have preferred there was some notice so you had more time to prepare...and I hope that this won't be the only time you can get these cards...
Oh and just countered your trade with a couple of my hoards...not that I'm trying that hard..just don't think I'm gonna have the time to chase the trades to get the numbers needed...
I haven't really worked out the green / pink / orange yet. Pinks only seem to be available as purchases, so I won't be chasing them. As per in game message - happy to trade you green or orange if you are looking for particularly characters, even if mine is single@tangent .... you didnt mention your greens??what do you want for them? lol
