From the cards you said in your first post I only have 1x Carrier thrall. Talking about green I have 2x evolutionary leap and 2 eyeless whatcher... I also have 2 undercity troll 1 zendikar incarnation and 1 zendikar's roil so you think any of them would be valuable??
None of the green stuff you mentioned is worth converting this deck into Jund (B/R/G), IMHO. It will slow you down a little to add a 3rd color and none of the additions would benefit your deck enough to be worth that cost.
Evolutionary Leap is debatable, but isn't enough motivation on it's own for me personally.
What might help you is adding some
Bloodflow Connoisseurs (contextually can be better than a husk, but usually isn't - though still giving you a free instant speed sac option which is something you want more of in a deck with a bunch of myrs, arsonists, and some treasons),
Blazing Hellhounds, or even
Voracious Nulls (worst of the sac option creatures to have, with the AI's reprisals looming and sorcery speed (1)B sac ability activation, but at least it's
something). In your current deck, if you don't draw one of your two husks, you're hurting.
If you do go more sacrificey, you'll probably want to add more
Act of Treasons, or even
Traitorous Instincts if you don't have enough treasons. Instinct will be harder to use in combination with hellhound or null, but against the hard AI it shouldn't be too much of a problem for you to get to a point where you can do that before you're dead. I wouldn't go that route unless you do put in more sacrifice options in the form of permanents, but if you can do that, those steal-for-a-turn spells will turn into SfaT + removal spells and add insult to injury.
