I disagree with almost everything you say here.
What are you basing this on? Nethervoid costs 4, and its black. And how many decks that run decay, do we want trinisphere against anyway?
What 2 critters, aside from DRS do you want the totem for? Elves and Griselbrand activation? I dont think this is the time for it.
cutting crucible is questionable, i would at least play in the board, for those obvious times when you want to take out some loam/intuition deals.
