I just hit KoG with Yubel mill in a format full of Koaki Meiru no-brainers. I won 12 out of 12 games vs Koaki Meiru through Legend. Dont hate on this deck only because it does well into your Meta trash. The only thing this deck struggled with was e-con and U.A./Amazoness banishing Terror.
No Ebolas at all. 3 Limit Reverse, 3 Worms, Yubel engine, Yaksha, Island and Canadia/Floodgate.
Limit Reverse renders e-con useless if they cant follow up with destroying your re-summones Yubel in the battle phase. Also helps milling with summoning Worms from grave. This deck had me thinking harder on my moves than stupid Heros or Koaki btw.
My recommendation is to not use sphere ebola but regular ebola instead. If you’ve got shallow grave use that, Ultimate nightmare will do its best to neutralize the shallow grave downside
Using regular Ebola vs Sphere Ebola let’s you survive armades and U.A slugger by affecting you vs changing their battle position.
