I support the idea of a 2 vs 2 game mode; I would personally like to learn from a more experienced partner (like Pit or Dubrovin, for example)...
This way, after a few games, you can really improve your skills, if only because (as mentioned above), you can observe your partner's moves.

When I first came to the site, I also suggested the idea of a 2 vs 2 game in the "Team Duel" thread, but nothing significant came of it. Could we actually organize this type of game, or even create a tournament?
