This will probably be my last post in this thread, because some people I'm discussing this with seem incapable of understanding the difference between playing the game and playing the game well. Anybody who knows the rules to the game can play the game. Not everybody can play the game well. It takes thinking ahead, planning, strategy modification, resource conservation, etc.
Durant makes that gap between playing and playing well so small it's almost non-existent. Durant uses the same strategy every time, and all the rest of the decks use the same strategy against Durant every time.
For the last time, it's not that Durant is unbeatable or too good of a deck. It's that the times it loses are often because the opponent's opening hand was too strong, not because it was outplayed. In a game like Pokémon, the person who is the better player should come out on top most of the time. That often doesn't happen with Durant. And if you think it does, you probably just haven't played against good Durant decks.
