She's a new player to the Pokemon series, but here's my plan. Customize a copy of the game for her - all TM's, huge amounts of money, and everything she needs.
What are the new events that she should have?
I'm going to include:
- a lillpup with all of the fangs
- all 3 starters
- the Victini wondercard
- the Mew wondercard
- the Mewtwo upcoming event
Edit: I just got her a valentine's day card and a copy of Katamari Forever for the PS3.
I will heed all of your advice and just get her the Victini wondercard (since she missed that), and the lillpup with fire fang, ice fang, and thunder fang.
