You break one of the rules of the game. This usually results in the opponent's Pokemon getting a penalty attack, and if you commit another infraction for the duration of the battle you risk getting a red card, or taken out of the battle.
the wonder card can only be obtained through a Nintendo event
Stark Mountain does not exist in Pokemon Yellow. It is only found in Diamond, Pearl and Platinum
You can't get aLeafeon in Pokemon yellow because it is not from that season, you can get one in diamond, pearl, or platinum though
buy it at the rare Pokemon store
Pokemon pearl ds card is smaller then a action replay
The Member Card is an event exclusive item on Pokemon Pearl. However the event to give the Card out is no longer being held. This means the only method of getting the Member Card is with a cheat device.

To get Kanto region Pokemon (Yellow takes place in Kanto), you must migrate Pokemon from the GBA versions of FireRed and LeafGreen.
