Not great but lifegain is a good counter to burn decks
This explosive ramp makes it easy to follow up with a massive threat like Ulamog, the Defiler shortly after Ultima hits the board
Lifegain is a traditionally white mechanic, but seeing it in mono-black with such a unique perspective is as interesting as it is exciting to play
Instead of some of the pricer options in the deck, I would purpose Wurmcoil Engine is a very good option with being a 6/6 for 6 with useful abilities, who creates tokens when it dies
Or even more gutting, simply not being able to take than Ugin
Whenever I come up against Edgar Markov, he typically doesn't even hit the battlefield until well after turn six, because players tend to build up dangerous board states before bringing him out
