I feel the weakest part of the deck is just there's so much hate in every single sideboard that makes winning game 2 and 3 a losing battle, especially in a long tournament. Eventually, there will be a game where I would just not draw Nature's Claim or they draw multiple Stony Silence, Rest in Peace, Ancient Grudge etc. and I lose. I have had a bit of success with transforming into an Eldrazi deck by adding 4 Eldrazi Temple, 4 World Breaker, 4 Thought-Knot Seer, 2 Ulamog, the Ceaseless Hunger and an Oblivion Sower and taking out most of the combo for games 2 and possibly 3. It's not as fast as a normal colourless Eldrazi but they draw dead graveyard hate which makes up for it. The Eldrazis also have cast triggers to deal with control, another hard match-up. Stony Silence still hurts a bit but it's not the auto-lose it used to be without Nature's Claim.
It's a shame this thread is losing activity because it's so fun to play. I've been thinking about how to make the deck more consistent and I've been doing well with the following list:
The main difference between my list and the usual is that I'm only running 7 eggs with 0 Chromatic Spheres. I only need 1 egg to start comboing so I don't see the need to run so many eggs, and drawing into multiple eggs means I'm wasting turns cycling through them to draw into the other pieces instead of winning. Instead I am running more search and draw effects with 3 Glint-Nest Crane and 3 Thoughtcast to add consistency. A common complaint of Thoughtcast is that it's too slow, but casting Thoughtcast by turn 3 or 4 for 1 or 2 mana hasn't really been a problem and having more cards means I can find the sideboard answers more easily and force spells through counter magic.
The main issue I find with the deck is that it's near impossible to win through Stony Silence and to a lesser extent, Rest in Peace, if I don't draw the Nature's Claim, or if they just draw more Stony Silence/Rest in Peace than I do Nature's Claim. Currently tinkering with a transformational sideboard to beat the down with Eldrazi's instead of trying to counter their enchantments.
