Notes & Combos

I did not realize the Fusion Cup's top level was 18, so I guess I'm finished!

This was the deck I used the entire time, no changes. Fairly standard go-2nd GK. Playing the Lunalight fusion for the Lunalight matchup(since I can't play Light Dragon), and it actually came up once and helped me win the game. Honestly a really solid list. Didn't have too much problem bricking or anything. I started at lvl 11

Branded was my easiest matchup, Hero the hardest, and that was mostly due to bad hands/bad luck. Dracotail was in the top 3 most encountered decks, and it usually went in my favor, but was definitely more of a toss up than Branded. I also faced a lot of 60 card Branded decks. Like way more than I encountered 40 card lists. Of my last 20 games, I went 16-4.

My last game was against Lunalight and they made me go first. I can't believe I won.
