We sacrifice Phyrexians to cards like Keskit, the Flesh Sculptor or mill them with Blight Titan, then reanimate them efficiently with cards like Victimize
One more thing, clones work well too as long as they copy the whole card like Mockingbird or Phyrexian Metamorph, and not a token shell like Skyclave Apparition
Sadly there are no other formats I can find that have any actual news about them
cards that act as your resources exist outside your starting deck and accumulate naturally, so the game attempts to eliminate issues like mana screw and mana flood, something you see often in non-MTG TCGs like Lorcana
