The most surprising entry on this list. Uldaros Theorix is a six-mana 5/5 flier that turns a stocked graveyard into free spells: when you cast it, it exiles up to one nonland card of each card type from your graveyard, copies them, and lets you cast copies with a total mana value of 6 or less for free. That pairs naturally with Dimir self-mill, and suspend cards with no mana cost, such as Ancestral Vision and Inevitable Betrayal, have a mana value of 0 and cost nothing from the budget. Syr Konrad, the Grim pings the table whenever creature cards are milled or leave the graveyard, and Thassa's Oracle closes with an empty library. On paper this is a strong value engine. In practice, the six-mana cost, the need to recast Uldaros to reuse the trigger, and vulnerability to graveyard hate are keeping early adoption low.
