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
On paper, it seems pretty balanced and self-restricting, for sure there won't be any oppressive card with this ability
It plays best with cards like Anikthea, Hand of Erebos and Starfield of Nyx that want enchantments in your graveyard
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
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
Sacrifice it at the beginning of the next end step if it has mana value 3 or less
