(Megamorph, the alternate-reality version, was not as much a hit.) I really like how manifest shows that you can take a core good design idea and extrapolate it to make something related, but different, that's equally fun
Ulamog, the Ceaseless Hunger 7 New Ulamog is a fair bit better than the old in these kinds of application
The decks have less than a $10 difference otherwise, which is negligible
As for uncommon payoffs, the deck has some nice legendary creatures like Uncommon payoffs like these are a real draw for an archetype like this since you'll have cornered the market on them
For Commanders that can afford it through cost reduction like Rowan, Scion of War, or Treasure generation like Prosper, Tome-Bound Crackle with power can end games in an instant
The theme here is consistent: if you are willing to invest in a longer game where you stretch your Stage Two plays through turns 5, 6, and possibly beyond, Orzhov is going to reward you with cards that are good against both conventional attacks and predictable control elements
