Yes I would, I was going to run one after the other xbox tourney but if someone else was willing to run one I would play. Do you know what the format would be?
The main question I think is whether you want this to be a test of adaptability, or deck building.If it's adaptability, then you allow deck changes between rounds. If deck building, then you must keep your combo throughout the tourney (although you can change the build between rounds, as it'd be impossible to police that)I personally think keeping the same decks is better. Not everyone has all the decks unlocked, and you open yourself to counterpicking otherwise, with the people who have unlocked everything having an advantage.
I understand about builds but if you are playing 2 out of three you should be able to play with a different deck the second game. I dont see the point in not allowing the players to swicth decks .Also to post your decks that you are using gives ur op a chance to build around it.
