@Deoxyz and @theSLAYER, I am being told it might have been only X, or only Y. So even though the cards have both games flagged, the servers only served a specific card to a specific game, and half were broken. I wonder if there is a way to prove this.
You are more than welcome to. We will get it once it is posted on the servers (usually before the codes can be redeemed). Also thanks for the info, I didn't even know.
I wonder if Bulbapedia has that info? (@SnorlaxMonster)
Fun tidbit, Celebi's wonder card ID is 251, like it's dex number!
Also the final Korean Celebi card was uploaded and it matches the last test card from a few days ago.
