Clearly you aren't up to date about this deck. Last months KOG decks showed a Hazy Flame deck where a cheat toggle button was showed in the screenshot. Nobody said this guy cheated, they just made a funny comment.
WTF is this deck , hazy is tier one with 3 floodgate and econ to counter bunch of things , bug is fixed alright , use this deck with skill then this is one of the strongest meta . You're the dumbest rater I've ever seen lol.
It's really not hard to make a deck better than this lol
I don't know whether sphinx bug has been fixed or not. But playing this deck on the normal duelist its pretty efficient molten zombie combo with sphinx getting plus play plus if we need more atk power there is always molten destruction as an alternative as suppose to using fire king island. At least it helped in my case
