I went ahead and combed through old Amonkhet and HOU cards to upgrade the Temmet precon.
Restriction was only zombie cards that reference Amonkhet or have mummy art. So Varina made the cut due to the sol ring flavor text, and Vengeful Pharoah barely squeaked by.
Cards like Archfiend of Ifnir and Scarab God are for now not in the deck due to this restriction. I may add them later.
It’s definitely still a battlecruiser deck, but there is a lot of synergy in the block between the cycling and amass mechanics, and I think it’s more flavorful than the stock precon.

(You may cast this card from your graveyard for its flashback cost. Then exile it.)

: Mutavault becomes a 2/2 creature with all creature types until end of turn. It's still a land.
