My bad. I assumed the decklist in the opening post was the most up-to-date one; I have now made myself read some more of the thread

I see you also cut back to 3 Presence (and 2 Replenish) in later lists, that's also the decision I was closing in on.
Cutting the Fertile Ground is something I also often do post-board, but I have to admit it has been nice in the Blood Moon Stompy matchups - often managed to win due to being able to play all my spells through a chalice on 1 stopping Sprawl, and Moon stopping everything else (esp. due to my black splash with only 1 basic plains - I guess in the 2 colour build it's less necessary)
