No problem, great deck name btw. Don't forget that hedron crawlers count as 2 types towards delirium.

Holy shit you're absolutely right. That's amazing.

so instead of Shaman of Forgotten Ways I would switch it out with Somberwald Sage as well as maybe add something to protect you from those Vapor Snag / Path to Exile.

JuhnZeiFox This is actually a standard deck but those are good suggestions if I want to end up turning it into a modern deck at some point. Thanks!

Lol awesome name! Cool build too. My only concern would be that Kozilek's Return kills all your rampers and is usually played early to take out tokens and humans. You may want to relegate them to the sideboard for Aggro opponents or throw in some more non-creature "ramp" such as Oath of Nissa for a turn 1 play to find a key land or creature, or Hedron Archive to ramp early and provide gas later. I would also stick in a Dragonlord Atarka as she just wrecks boards. I do like Shaman but he's a bit fragile. If you added blue, you could use Kiora, Master of the Depths with Shaman to super-ramp (untap him and a land, if that land is Shrine you'll end up with 8 mana to spend on an Eldrazi) I like your style! +1

Thanks Jimmy_Chinchila! I think Oath of Nissa will help me out a lot in both the early and late game. I really like Dragonlord Atarka a lot too and I'm going to start trying her out. I'm a little hesitant about adding a 3rd color specifically for Kiora but these were all great suggestions and I appreciate it!

Cryptolith Rite seems like a possible mechanism to also help you get Ulamog out a bit more quickly. Beastcaller Savant would be good for mana as well. You have a lot of expensive creatures that you're trying to get out and you have removal and some mana ramps to help, but why not some creatures that also bring along Scions? Brood Monitor could be useful. It's also expensive, but with three 1/1 scions, the next turn you could get Ulamog out.

Mage-Ring Network could also work to your advantage. You could charge it while waiting for Ulamog to show up and that would allow you to get him out a bit faster.

To slow opponents, some mana destruction in the side might be useful. Crumble to Dust or Structural Distortion would be useful. Crumble to Dust is especially powerful if you're playing against decks that rely heavily on dual lands. It's a great way to completely mess up the opponent's mana curve.

really nice green red deck.
