When i am playing in a tournment you ovious play diffrent people who arent in your play group (oviously in big tournments) which makes it a great experience see how they have made there deck etc.
What i find though when you do come across someone from your play group you know exactly how the game is going to go. Its like at the uk ptom my last 2 rounds where against people from my play group and i lost both games know exactly that would happen (those loses were my only 2 out of the 5 rounds) but i dont like that fact as your play group know how your deck works fair enough you do as well but if your like me all you know is when your dead or not or if you can do something.
I find play diffrent people a new experience and more fun as you dont know whats going to happen and i feel like i stand a chance. I spose the question i am trying to ask is whether you find play people from your own play group in a major tournement a good thing or a bad thing win or lose?
