Glad AW came up with a solution to the "Turtle then heal up at the end of the game Problem".
...Not sure how I feel about it though. It certainly encourages an aggressive playstyle geared towards dealing damage in the fastest most efficient way possible (a playstyle I do enjoy!); however, this format excludes other strategies such as the wizards mana denial or any strategy that plays out over the "long game". IMO It really changes the game. I think this format will will create a meta-game that revolves around a few obvious strategies: Early "big" expensive creature rush, melee equip builds, and blasters....I guess I'm okay with that.
After they nail down exactly how the tourney scene is going to function, I hope they come out with different play formats that encourage other more diverse strategies.
