Sennet Millennium

Nothing set in stone quite yet (other than the Millennium monsters). The basic idea is to treat Millennium as a secondary rank 8 engine to set up Zombie Vampire to both fill your graveyard with Sennet cards and normal monsters, and also hopefully find Nefertari to get your plays started if necessary.

The Millennium engine is very versatile in this deck, getting you access to a normal monster on your field while dodging most conventional hand traps via Wedju Temple placing Millennium Golem face up directly from deck. Although the Sennet cards turn normal monsters into equip spells, they don't actually care what the normal monster is being treated as for the sake of their effects, so your normals being continuous spells makes no difference for your Ritual summons. As part of the combo to make Zombie Vampire, you also make Snake Eyes Doomed Dragon by sending two face up monster cards from your backrow. This can help get normals or even your ritual monsters in the gy without activating any effects from your Sennet engine if your opponent is primed to disrupt that half of your deck.

This is a temporary list I will be revisiting to adjust. Some non-engine or the ratios of the Millennium engine are likely to change.
