Hey TaWooOneTime, thanks for the input. I really don't know what I am trying to do entirely, I am terrible at building decks, but like the Athreos a lot. The deck is mainly Black Aggro I guess, but the Gary is too good late game I thought to not have at least one in there. The reason I have the Vizkopa in to have a mechanism to gain some life back via lifelink. Or even double down on an attack with lifelink via Master of the feast or Athreos, or via Gary/Debt.
I realize the mana is not correct, I just had 25 swamps for a place holder. Thinking: 4x Godless, 4x Temple of Silence, 4x Temple of Malice, 4x Blood Crypt, 8 foil swamps, and 1 Nykthos. Other option would be to knock down on some temples and replace with Mana Conflux and more swamps.
Again, I appreciate any input. I am trying to build something that I love playing. I like Mono Black devotion a lot, but don't want to play the same thing as everyone else.
