Black or Green?

[Destore117]

Looking to build a new 3 color deck {W}{U} and {B} (or) {G} and was wondering what people prefer black or green? The deck as is runs heavy enchants with {Fencing Ace} and blue for unblockable/counter spells using black currently for removal and life gain but want to put in green for things like {alpha authority} and {Spider Umbra} / {Rancor} / {Snake Umbra} and also for nabbing lands from my deck. Also using artifacts 2 {Trepanation blade} for buffing fencing ace and 2 {elixir of immortality} for stopping mill decks.
Opinions? Should I keep black or swap to green?

I like esper a lot but since your running heavy in the enchantments I would go bant for sure.
