Not a bad deck, it has great consistency, a good theme, and it looks like it would flow well. The only negative thing I have to say is that I usually tend to advise against running single-color decks, because it is so much easier for an opponent to hinder you if you do not have another color to fall back on. Other than that, very nice deck!

Used this deck for the first time last night, ROFL I lost but it took 3 people to take me down haha, At one point somebody just blew up their disk so two turns later, I emptied my mana pool and tap all my lands.

Play) Spawnsire of Ulamog then activate it's ablity and drop 8 eldrazi down hahahah lol.....then i got direct spelled to death hahahahahhahaha, it was so one sided tho and if I had more then 4 life I would of took it.

The other problem is I didn't put my Kamahl in there, but it is now.

rofl if it took 3 people to take you down hell u should try an edh archenemy game. that would be pretty intense. as far as your deck goes u will thin out ur deck in no time im assuming with all the ramp u got going on. and u can just build up a ridiculous amount of mana just by tapping out and letting omnath get bigger right?

ya tap out and let it build is the key. It doesn't take long until I start to general people out with a trample (often unblockable) mofo, and I thought about how playing him into Greater Good can be broken. Let's say I have omnath at 20 mana, I tap and sac him to GG and draw 21 cards, and have 20 mana to do something with, I can play him again and sac again for another 15 worst case!!! This combo just dawned on me recently and is begging to be played.

I really like this deck. I have an Omnath myself but I based it off a big beater 60 card deck I used to have so its a bit different. The only cards I would suggest using would be Helix Pinnacle, Rofellos, Llanowar Emissary (sick mana pump), Praetor's Counsel, and Myojin of Life's Web (sick recovery with counsel after a board wipe). Just a few nasty little goodies that worked well in my deck.
