Late-game, when everyone is looking to close out the game, then it seems fine
Essentially its a pay to win game and only in a very tempered group that sticks to formats and limiting budget does the game become reasonably fun
Marchesa, the Black Rose : When I build Marchesa decks, I use plenty of creatures that naturally enter the battlefield with +1/+1 counters, which means that, with Marchesa, the Black Rose on the battlefield, we can feed one to emerge without going down a card
It plays best with cards like Anikthea, Hand of Erebos and Starfield of Nyx that want enchantments in your graveyard
That Bonder's Ornament will be surprisingly useful when you find yourself needing an answer in a couple of turns
One possibility is to cast Apocalypse, a card that gets rid of everything, including your hand, leaving you only with Barren Glory, but that needs to be done on your upkeep, so there are options like Leyline of Anticipation or Emergence Zone to give these spells flash
