Notes & Combos

I couldn't play the game for a month due to some personal issues, but I climbed from Platinum to Master again with Gem-Knight, and the climb was really smooth. I'm not fully familiar with the current meta yet, but the biggest problem right now is Elfnote and the slop variants with Centurion, Kewl Tune, and White Forest.
