I had my shop challenge, running Vanquisher, and did better than I ever had, but not good enough to win.
Game 1: Against Big Boss, Guzma. He 0-2'd me with Raging Form, so I lost.
Game 2: Scharhtot. Holy Gille De Rais, this took forever. We ended up with the three turns each happening for the entire third game. 2-1, a nice win for me.
Game 3: Gavrail. I was excited from the last round, but was able to pull out a 2-1 win, and I used Chain Bolt for the first time. Look it up because it is powerful.
Game 4: Ahsha. Nope, this was an 0-2.
Then cut to top 4, and someone told me that I had a huge chance of getting in if Guzma won that round, but he lost, and so did I.
I did walk away with the Aichi folder, though.
