I just dueled the Dragon Ruler deck and finally got to see it for the first time after hearing about it for a while… Looks way more broken than Mermails to me lol. How can Fire Fists even compare to these decks, idk lol.

The counter to them seems the same as Mermails as well: Cosmos/D-Fissure/Banisher first turn = Gg. They rely heavily on the graveyard.

On a side note, D-Prison / Solemn Warning if you set it before they play Dracossack, is the only counter to Dracossack that I know of :P. You can also Fiendish Chain/Breakthrough Skill it, then use something else to destroy it once and for all, so I guess Dragon Rulers aren’t insanely broken either. They just seem that way because I got owned by them with my Fire Kings deck  which I am still thinking about playing competitively despite. I will just throw in Fiendish Chain and D-Prison lol :P. That will counter them ok-ish lol.
