Sorry to ask so many questions... I will shut up with questions after this.

1. You don't get experience for battling these trainers, do you?

2. You don't get to keep an item that you steal from one of these trainers while battling them, do you?

3. It is my understanding that every time you scan a new enigma berry card, all of your other enigma berries from previous card scans are replaced with the new kind of berry... is this true? If so, well... it really sucks! I'd have to trade them over after scanning them in another version to avoid my previous ones getting deleted...

4. Can these e-cards be scanned multiple times?

Thanks.
