-4x Realms Uncharted for 4x Explore . The ramp AND card draw are necessary for Tron. Tutors are great, and you have plenty, however card draw you have none of.

-4x Not of This World (decent sideboard card) for 4x Prophetic Prism and/or Chromatic Star .

Ancient Stirrings is another great tutor, as it can net land or colorless spells.

Wurmcoil Engine is a must. Replace the weak Eldrazi with him.

The other Eldrazi, Emrakul, Kozilek, and Ulamog are also great freaking cards that could be here, pending budget.

I would highly suggest you splash another color for some added disruption and interaction. Tron, and other ramp decks like 12 Post, don't do much the first few turns except draw, tutor, and put lands into play, thus are vulnerable to Aggro.

This is a rough idea, but it's my idea of a R/G Tron list:

thanks for ideas, don't want to pay for Wurmcoil Engine , and i just can't find anything to replace with Ancient Stirrings , everything else is great though

I'd suggest you check this out.

It's a list of all of the recent top 8 Tron decks, G/R is a typical incarnation of this deck and that list can give you far better pointers than I can. My specialty is UTron: I Fight For the Users!.

If you want to stick to mono-green, I would lose some of the eldrazi. For tron, you only really need one or two big eldrazi to close the game, since you can search for them with Eye of Ugin , which you find with Expedition Map . If you have any of the three titan, I suggest using them as a 1-2 of, and take out the ones you have already.

In place of them, I would put in Wall of Roots , as an early defender+mana ramp, 1-2 Beast Within to deal with trouble permanents, and some artifact based mana ramp, like the ravnica signets or Talisman of Impulse instead of the more expensive Reap and Sow (since the LD effect isn't relevant, and it's not worth paying 4 to search out a tron piece).

I would still think about All Is Dust , even though it's not a budget card, since green can't really do board wipes and you don't have many options. Karn Liberated as a 1-2 of is also a good way to win a game, and at the very least provides advantage.

First off...Run more copies of Karn Liberated . Since you can drop him on turn 3 you cant go wrong with running more if you can afford to.

I would only run 1 Eye of Ugin since you can fetch it with the Expedition Map

Kozilek, Butcher of Truth is my personal faverite elderazi.

I dont think All Is Dust should be removed. I highly advise against that unless your on a budget.

Pristine Talisman and Prophetic Prism are taking up space that could be used for other things.

I am surprised to not see Wurmcoil Engine or Batterskull everyone prefers 1 over the other but either way you get to drop it on turn 3. They can also help recoup the life you lost before turn 3.

It That Betrays Pathrazer of Ulamog Ulamog's Crusher All these could be replaced with better Eldrazi and you also don't generally need that many copies of any given Eldrazi. If anything I would consider taking a different approach and putting Eldrazi Conscription on a smaller creature before running that many copies of any Eldrazi. It That Betrays if this one stays in the deck then All Is Dust would be better then Oblivion Stone .

Some other suggestions that I personally use in both of my tron decksPhyrexian Metamorph Lodestone Golem

Crucible of Worlds would help you if someones got land destruction.

Heres links to both of my tron decks if you want to check them out for yourself.Elderazatron is my Eldrazi version and Collosuatron is my all artifact version.

And one final thought. Pithing Needle pisses people in my playgroup off.

I tend to agree with what most of ninjaking92 said.

Definitely needs Wurmcoil Engine . And I agree that one of each of the mythic Eldrazi would be great. The lesser Eldrazi are just that. Go all out.

All Is Dust is a beast, except against Affinity/Robots, which you side in Creeping Corrosion for. Needs to be here.

Pristine Talisman could be Tooth and Nail or Ancient Stirrings . You could really use some more draw/tutor effects, IMO.

Lastly this could really use a 15 card sideboard.

For drawing I like Ichor Wellspring

Cool deck!

I would personally go up to four Karn Liberated , definitely the best possible thing on turn 3. Also, I think that It That Betrays and Ulamog's Crusher could be replaced by either of the other two legendary eldrazi and/or Wurmcoil Engine in any combination.

I think you don't really need It That Betrays - perhaps another Eldrazi?
