To play magic online, first see this thread, the details and links for the download are here.

Now, if anyone is ever online and fancies a quick game or two, just log on and look on after selecting your deck.

Look out for a game listed with an LO tag, and if there isnt one there, make one yourself and wait for an opponant! (alhough people may go afk.. so quite a bit of patience and waiting may be needed) But if 2 people are around at the same time, its an easy way to find each other for a game.

Be sure to include a join note stating that you are an LO member when requesting to play a game.
