I feel like biomass mutation and faerie impostor are not good in this deck. Biomass late game isn't going to do much if you're manipulating your counters how you should be and faerie impostor you're not gonna wanna play most of the time because returning a creature to your hand will remove the counters you've been adding to that creature. I'd add some control or card draw, you only have 1 prime speaker to draw and no control at all. I'd also add a prophet of kruphix or two because its an awesome card.

Hey, I like the deck and I'm definitely no expert at magic considering I just started playing again a couple months ago but I'll just give my 2 cents on this. First, you don't actually have abhorrent overlord in your deck, but mention it in your game plan, I'd take out the lifebane zombies and put them in your sideboard cause they're more counters to specific colored decks. I'd also use hero's downfall in your main deck and put doom blade in the sideboard because if they are playing against planeswalkers or black it'll be a useless card. I don't really understand the purpose of boon of erebos in this deck, I think return from the underworld would be amazing with this amount of devotion, and if you discard abhorrent with pack rats you can get it back from the graveyard for 5 instead of 7 to play it. Lastly, if you're going to use underworld connections you probably want a bit more mana because it uses your mana to draw.
