Notes & Combos

Rock don't think. Rock play Lightning Storm chain Forbidden Droplet.

A surprising number of people have no idea what to do under mulcharmies

Gem-Knights break through half-boards incredibly easily so getting your opponent to stop playing by a Mulcharmy, MaxxC, or Lancea is top priority. If you don't draw them against full Maliss combo you lose unless you draw at least 2 breakers.

The Shaddoll package only feels good against Ryzeal, and Maliss is the top deck so I'm not playing it. I'm playing CalledBy because in some hands Lancea can ruin my OTK, but that might just be a skill issue on my part. I switched it out for Ultimate Slayers at the end of my run.
