Everyone's playgroup meta is going to be different, but Culling Ritual is one I would think twice about removing. In context of these precons, when playtesting, it really helped to slow down the Eldrazi Deck. Played it two games, and was able to hit 5 mana producing permanents on the Eldrazi board, while only hitting one thing on my own. It did get countered the second game though.
It may not be good late game, but it was great early game before I had a lot of tokens out.
The deck has been fun to play so far.
