No one posting? Okay...
I would personally like it if people were forced to show what thier decks were on the fourms as they made it, more so with MvsM.
It could create a bit of a mindgame. And make the teams feel like teams.
"Yeah, I'm a man! I'll just PM this deck..."
"Okay, I'm an FG. I need to make a deck that counters this deck, this deck... You know, Frozen's doing some terrible little dune scorpion... thing... Oh, that SoR rush looks... ugly... I'll try to accomidate that little special chaos power inside of it..."
(... That was the worst improvisation I think I have ever done... SoR + Chaos power? Really?)
See my point... It just feels more... not better, not elegant... richer.
