It was fun to play, well it still is. It gives people a chance to play it without actually buying the cards. Well I'm not a expert on TCG so I cannot really judge about the decks themselves (though reading through the comments they must be pretty bad, well I'm happy with an UU deck then). Also, I live in a country were TCG tournaments are rare, extremely rare, so this game is pretty neat.
EDIT: Of course, just after I said it was fun to play my internet decided to disconnect while being in a match. How unfair?
