I can't believe I'm asking this but where can I play with the Gundam starterdecks online so I can teach my friend? He plays the game, I don't. He feels like he can't win any games. I'm serving as an ambassador from the competitive scene to help him get some Ws.

Secondarily, please if anyone has the time, could you offer some newbie advice that I can pass along to him? Right now his local scene only plays with precons, so I don't need to get into advice on deckbuilding or high rarity evaluation yet. We're talking fundamentals and how to actually succeed at this game, such as this.
