Where can you download Magic The Gathering games for PC

It depends on what type of game you want to play. If you're just looking to sit back and play with some pre-built decks in a pretty environment i'd recommend "Magic the Gathering: Duels of the Planeswalkers 2012" on steam. If you want to get into a very complete system, with every card and you dont care if you have to pay for packs or if the graphics suck, id recommend "Magic the Gathering Online", basically its fun easy pretty game vs expensive, detailed, serious game with more options than the first.
