Would Chord of Calling work in this deck as an additional tutor option for the combo ? The triple-green doesn't seem that easy to hit.
The deck is creature heavy but most are black (can't help with green mana for chord) and some are meant to be discarded rather than cast.
I'm also looking to replace Hunted Horror as my secondary scavenge creature for something I can actually cast and Nyxathid seems like the best alternative, Phyrexian Soulgorger can also be used as a 1-turn blocker and maybe even attack once (if I sac' a Birds or another creature).
Is it a good idea ?
That's funny. I actually started working on a similar deck about the same time.
I played a B/G scavenge deck in standard during RTR and it's my favorite deck I've ever played. So I wanted to recreate it for modern. It's a shame Deathrite Shaman is banned as it was a pretty important piece.
Anyway, this is what I've come up with so far. I think Jund is the best option as opposed to straight B/G.
Have you considered dredgers like Golgari Grave Troll? It would make an easy way to discard a creature to troll every turn as well as help fill your yard with cards like Death's Shadow and Hunted Horror. Seems like you aren't quite getting the advantage from your yard as you could. Not sure I like Phyrexian Crusader as a scavenge target, but it could be fine being pro red/white.
Cryptbreaker could be good for the card draw, but I feel like it might be a little slow for modern. It also doesn't get bigger by any ability of its own, and it's not a good scavenge target, either to be scavenged or scavenged onto.
If you want more draw, with the low curve of the deck, I really think dark confidant is a good choice. If you can stomach $40 per copy. Doesn't let you discard or have the zombie creature type though. Also, if you want more GY fuel, Splinterfright costs 3, gets bigger as you pitch stuff, has trample and puts two cards in your graveyard each turn.
Here's what mine is evolving into, though I still haven't gotten to test it against a live person yet.
Borrowed your Inkmoth Nexus idea, so thanks for that! My primary concern at this point is having a troll that I've put so many resources into getting exiled, or neutered in some other fashion. So I put 3 Spellskites in the board. I think it's a good option as these kind of decks tend to put most of their eggs in one basket.
I have a problem with continuously tweaking decks I've yet to play... Haha.
What do you think of Liliana, Heretical Healer? You can trigger her to flip by playing death's shadow at anything >12 life. She will also trigger if you sack something to regenerate Varolz, in my case she will also trigger if they take the 4 from Vexing Devil, allowing you to put things you need into the graveyard while simultaneously wrecking their hand.
I would suggest cutting some of the 4-ofs in the deck since you have the tutoring power of Fauna Shaman and Eldritch Evolution. Also Spellskite is good to have because no matter how much P/T a creature has it can still get hit by Path to Exile or Abrupt Decay. More discard would probably be a good idea.
It seems a bit slow and: P.Crusader (pro-red), L.Troll (can regenarate) and G.Flayer with delirium don't really care about L.Bolt.
I might as well use Eternal Witness for this purpose.
Fatal Push can indeed be a problem as only L.Troll with regeneration mana up can survive it, and it kills an Inkmoth as well.
But I have some discard spells that can hopefully help with that and "Revolt" won't always be available to kill P.Crusader.
