You say "best decks" as though "best" were a constant. The only consistent best deck is Threshold. Everything else is highly dependent on meta-game. So a deck doing really well in Germany has no bearing on it being competitive here. Consider Elves, for example. Maybe in a meta-game where the majority of the meta-game is Thresh, Landstill and Fish, and Goblins is less of a concern, Elves could be a competitive choice. That doesn't mean that I'm going to consider it when testing a deck to run at a tournament in Conneticut.
"Winning decks" do not equal "the best decks". This is especially true when comparing two very different meta-games.
The LMF can't be designed with the expectation that success in Germany is going to translate into future success in the US. American success is essential if we actually want to reflect what the decks to beat are going to be.
