Played this deck for my first game last night (opponents picked it at random). Although I didn't have my fastest start ever, my opponents initially weren't doing much and were being beaten down by small creatures. Omarthis came in as a 2/2. For a while, I had the best board position. Then the least experienced player at the table managed to get Vesuvan Drifter to become a copy of Dazzling Sphinx and chose to attack me. There were only three possible hits and my opponent probably had no idea what they were (Eldrazi Confluence, All Is Dust, and Rise of the Eldrazi were all in my library, while Desecrate Reality was sitting in my hand). She hit Rise of the Eldrazi, snowballing enough to become the biggest threat at the table. I worked to rebuild, using Threefold Thunderhulk to grow Omarthis. After dishing out a beating to all three opponents and taking one myself, I eventually managed to have Omarthis get hit by a removal spell, manifesting 19 cards. From there I was able to use Eldrazi Confluence to turn Ashnod's Altar face-up. On my turn, I used Ashnod's Altar with some help from other artifacts to manifest the rest of my library and to move 54 +1/+1 counters from The Ozolith onto Walking Ballista, pinging my opponents to death.
