Really been wanting to pick this one up ever since its release, but I've been waiting on a good deal for it. Glad I did.
To answer your question, the Duels of the Planeswalkers is pretty much an upgrade in the same regard that yearly sports games are. Each yearly version has new decks (that follow whatever sets were out and hot at the time) and new puzzles. Keep in mind you have to use provided preconstructed decks, and can't make your own from scratch.

It's the card game. Nothing more, nothing less. (Well, aside from not being able to completely build a deck from scratch) Bonus stuff is cosmetic in game and not necessary at all. Not sure i've ever seen 2012 go 75% off, but I can't say for sure. (Check steam price trend sites) 2013 is better than 2012 if you like the more recent expansions. IE - Different cards available for use between the two. Yes, online multiplayer.
