considering turning this into a jund (still be devour deck) deck with kresh as my commander. opinions?

I don't think you'd need to add Black to the deck, but it would provide better mass removal, so that is a consideration. Kresh is fantastic, and he certainly would work well with devour, but at the same time this Thromok guy might be less popular, and it's always great to see less popular commanders played (even if Thromok is really popular at first, like with all of the Commander product legends of last year, a lot get less popular as their novelty wears off).

I see some great cards here, like Ant Queen, Mycoloth, and Fresh Meat. Add to Fresh Meat Caller of the Claw . There are other much better token generators than some of the ones you have (e.g., Grizzly Fate), such as Avenger of Zendikar , Rapacious One , Beacon of Creation , Night Soil , Nemata, Grove Guardian , Rakka Mar , and Orochi Hatchery , just to name a few.

I would consider adding Kessig Wolf Run since it's just so good.

I would also tune your removal. If you find out that you need more mass removal, Red and Green aren't so great at that, but they have a few: Savage Twister , Blasphemous Act , and Chain Reaction , and I would run Oblivion Stone as well. Red has mass removal that will take out creatures without flying and Green has some that will take out fliers, but these are the ones that will hit everything in those colors (or colorless). There are also some decent pinpoint removal spells in the colors that you don't have to add, but I would consider, such as Beast Within , Fissure , Lava Flow , Bramblecrush , and [[Capricious Efreet] if you don't mind the randomness and having to target one of your own tokens. I like seeing Decimate ; it's an underplayed card in this format.

If you added Black you could run Grave Pact to make everyone else sacrifice creatures when you devour something. That alone might actually be worth going into Black. In which case you have better removal options such as Terminate , Wrecking Ball , and Putrefy for pinpoint and better wrath in Damnation (expensive money-wise), card:Black Sun's Zenith, card:Life's Finale, and the mana-intensive but good finisher in Plague Wind . I would still run O-stone, though, since it gets artifacts, enchantments, and planeswalkers too.

I hope my suggestions help! Red/Green (and Red/Green/Black) are a ton of fun to play. If you decide to go with the Kresh route, you'll be running a really common Commander, but you'll also be running a really good one; since the Thromok guy is so new I can't speak to his powerfulness, but I'm sure he'd be loads of fun.

I love him devour X? but thanks ill tweak it soon

need one more card. looks like had 2 rapacious ones.

what should i put in for grave pact and whispersilk cloak

The Dragonmaster Outcast , while a good card, is particularly difficult to use in this deck, as you have a limited number of mountains. I would take him out personally. Stalking Vengeance is a potential replacement.

Also forgot, I didn't see a Butcher of Malakir in here, he's usually pretty good in deck's like this

demy is correct in that Stalking Vengeance and Butcher of Malakir are great here. The Butcher is just a creature version of Grave Pact anyway, but a great addition to control the board. However, unless you're planning on having the Dragonmaster Outcast out on Turn 1 regularly, having only 7 mountains doesn't affect anything as it counts numbers of lands, not mountains.

I think ill put stalking vengeance in. seems like a devastating combo with thromok thanks for advice guys. really appreciate it.

Griselbrand was recently banned from edh, if that matters to you

shit really. i need a good card to replace it

If you need a replacement for Griselbrand , then Rupture is something to consider.

rupture is too dangerous for me. especially with what i use fling for. I'd rather something that is similar to griselbrand

Fecundity is the best replacement for Griselbrand in this deck if you don't mind your opponents getting cards as well. Another amazing option in this deck is Skullclamp .

If you really like Fresh Meat in this deck, you could consider adding Caller of the Claw .

Fecundity is redundant since by the time i do mass sacrificing i should already have draw. as amazing as skull clamp is i need sac fodder for this deck. took fresh meat out.

Need soem help to take out 1 card. I added more ramp since i had a major mana issue when playing with 75 % of this deck today
