Overall looks good, agree with ecpn. You've got some cards that are just fillers and not win cons. Drop those out for more synergy and you've got yourself a golden deck.

Conduit of Ruin would be good in this.

True, I was thinking more for the cost reduction then the fetch. Also, It That Betrays could be good, considering you have Ulamog and Kozilek

MasolinDoCora good template here.

@ KumaLKS There was a point where I had every huge beater in the deck, what it comes down to is you're typically casting Ulamog, the Ceaseless Hunger, Ulamog, the Infinite Gyre, Artisan of Kozilek or Kozilek, Butcher of Truth for the on cast effects and not to use as beaters. Don't get me wrong, the cards are great to destroy a board state, however, when you're dropping these bombs - you're most likely already in a win condition.

These are especially nice when you have 11+ counters on Animar, Soul of Elements and Cloudstone Curio out.

Craterhoof Behemoth out for Somberwald Sage - Ramp department felt much more important, fits into the other win con better.

Something about Craterhoof Behemoth just didn't feel right. Great card, just hasn't been a game changer. In many games it's been available as an alternative win con but definitely felt like a tier 3 win con, especially when other options were present at the same time.
