Notes & Combos

Blind 2nd is under-rated in this meta and backrow removal really shines. With Nibiru stocks tanking because the top decks either play under it or through it without issue, you can pretty safely use your HollowCore omni negate on something else. That alone gives gem-knights so much more potential to break boards.

Cut Perfume Dancer for a 2nd phantom quartz if you don't respect Lunalight, but it has won me a handful of games alongside Ultimate Slayer. I believe its worth it.
