Notes & Combos

I reached Master 1 this month with K9 Crystron.

Since the Duelist Cup is at the end of the month and things will probably get busy, I tried to push for it early, but the climb ended up being pretty tough. Still, I’m glad I managed to make it.

I honestly didn’t understand the meta very well, so it was hard to judge the deck’s position the whole time. I think I’ll study some other decks too.
