Notes & Combos

Gem Knights feels very strong, went on a few win streaks from D3 -> M5 despite being new to the deck. Charmies and Maxx C make your opponent either end on a half board or pass the turn back to you for an easy OTK. Shaddoll package was very strong especially into Ryzeal to deal with the field spell and Detonator.

I am thinking of swapping out the Bagooska for either Donner or Azalea as my only out for an opponent's Bagooska was Droplet/Talents take. Dugares, Bagooska, Lapis, the second Phantom Quartz, and Prismaura never came up but was likely due to me being new to the deck and not using all the Gem Knights properly.
