So I was looking for a low-intensity game to suit my mood recently and ended up going with Magic 2014. So far I'd say I've already gotten my 10 bucks' worth; a couple solid nights playing the campaign with probably a couple more to go. I'm just a little unclear, based on the game's presentation, how far that goes. Especially when it comes to the Sealed Mode.
Is the Sealed mode really a viable way to play the game if you aren't buying any cards whatsoever, or would it be too hard? Does it provide enough opportunities to add to my collection? (It looks like there are only maybe 3 more packs I can get just by playing the game, looking at the campaign screen). Can you buy addons to your "sealed" deck without buying real magic cards?
