This is roughly what I ran for the singles event. The deck is actually quite different from the previous build that placed 4th at the GCC, going back to the roots of EVIL for the main kill condition. Lots of card advantage in the deck with Lord of the Makai, Kabuki Artist, Blood Runs True, and The Gorgeous Team. With Billiard Player in the deck, I can afford to cut down to just the one Defender, sice I could get it back whenever I want with Billiard.
As much as I hate to say it, Knight Breaker is as good as it gets in todays meta. I can't tell you how many games where all I drew was an Ichi and two Breakers and that was more than enough. Ichi ->Breaker -> Breaker Combo enhance is a hard cripple to deal with and can usually put the opponent in panic mode.
One game I Defender Looped Ichi no Tachis with Reverse Flayers. One game I Defender Looped 2 Launchers. Another game I left the opponent with 2 foundations after a bunch of Breaker Death enhances (Seals).
One of the biggest play mistakes that I see everygame is Olcadan's Mentoring forms. The opponent would give me 2 or 3 Ant K' from my discard. You know what that means? Next turn your going to fail your blocks! 2 of my wins came down to Anti K' forcing the damage through with the -4 or -3 CCHax thanks to the opponent.
Soul Wave is definitely an auto include SIDE from now on. I think that there will definitely be enough discard in the new meta to warrant this in most sideboards. Bitter Rivals was SB to deal with Hanzokick.
Any Questions?
