Well, first off he couldn't add Shosetsu at the time cause when you started your Round the update with him wasn't out yet, and as per the rules you can't change your deck in-between fights only in-between Rounds. Though I do encourage you to use any new cards that come up in updates when it's available :3

And second, Luck is a very strong factor with this game, you can tune your deck so that luck is in your favor most of the time but you can't tune it so that it's in your favor all of the time. It happens when it happens and like with irl tournaments I won't allow do-overs so easily.

Still don't fret, cause the tournament is just beginning! Many many more fights to be had and more chances for you to shine! ^^
