How would you start as a magic newbie (Forge specific)?

Hi guys,
I'm a bloody newbie in Magic. In my real life I cannot and don't want to play against humans (yet), no Magic players I know.
I want to start against the PC and Forge seems to be the one and only appropriate software.
If you were a newbie, where would you start? There's the deck download in http://mark.tvk.rwth-aachen.de/software/forge/ - maybe you could recommend me some pre made decks. Also pls. recommend me decks for AI. Which game mode? I think cards should not be too complicated for a beginner. I want to have fun before going into "magic science"
For a romantic reason, I'd prefer to play something green or green/mixed... Often my user name in www is "Tapio", it's a forest god. I love the forest and also Sibelius' "Tapiola" masterpiece. Its a symphonic work. Tapiola is Tapios realm. All good reasons to go green
Thanks!
