Can't you get Yache berries normally anyway? It's "nice" but not a big deal. On a side note, the instructions are a little misleading. You're not just limited to 2 Wonder Cards. I now have a total of 3; Manaphy, Deoxys, Dragonite. The instructions say that if you have *more than* 2 Wonder Cards, you need to delete one to make room. For some reason, I had gotten the idea that you could *only* have 2.
