Notes & Combos

Another season reaching Master 1 with Gem-Knights; the deck responds very well against the meta, and the board breakers are excellent—especially Book of Eclipse and Lightning Storm. I had been playing Fallen of Albaz and Dogmatika Ecclesia, the Virtuous, but I decided to cut her because I didn't feel she was a high-impact card. I wouldn't make any changes to the deck other than running an extra copy of Gem-Knight Fusion, since drawing it is insane. As for the Extra Deck, definitely play Lapis Lazuli; the burn effect can win you plenty of games, and I always bring her out as part of my main combo.
