so, I may be completely missing something here... but can you explain to me why exactly you need fetch lands in here??? besides getting a shuffle out of it (which, I cant see a benefit to unless you realize that you should have scryed something to the bottom and didnt...), and maybe tricking your opponent into thinking you may have a few black cards in the deck, its not like you have anything in the deck that benefits in any way from having a swamp (which you dont have in the deck). why not just throw normal mountains in there, and not have to deal with paying life for a mountain that you could have just drawn into???

Fetch lands filters the deck allowing subsequent draws fore and more burn spells or creatures with haste to draw and less excess mountains.

I don't really play modern but this seems like a good deck

Thank you very much. I'm still playtesting this brew in my LGS. Very fast and very efficient no matter what color my opponent is.

I do have an occasional game loss but most likely I lost the game because of either wrong target of a burn spell, wrong mulligan, or either I have no answer.
