You realize how slow that is, right? Like tribute for Sphynx, then special summon some other monster, only to tribute that monster to only destroy set s/t, then return it to your hand at the end of the turn. You realize that this deck has no synergy and is slow as hell to play, right? Use your brain man!!!!!!
No synergy? All fire monsters, so all work with Sphinx's effect, obvious synergy between the fire kings, Yaksha can destroy Wild Tornados. Plenty of tribute fodder for Feng-Huamg to nuke the backrow.
It looks inconsistent due to how much it relies on sphynx, and sphynx being a 1900 Atk tribute monster, but there's plenty of synergy.
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
