After playing some games, I changed my vote.
I have found that what doms I keep depends on what deck I am running. So in a defense-heavy deck I run SoG, Grapes, DoN, FA, CM, Burial, Mayhem. In a speed deck I would run SoG, NJ, AotL, Grapes, GoYS, CM, Mayhem. And there could actually be some variations between these 2 depending on the deck.
However, in a balanced deck, and therefore what I voted for...
SoG, NJ, AotL, Grapes, CM, Mayhem, Burial. For that last spot where I had to decide between GoyS, FA, Burial, and DoN, I figured that GoYS and FA are not going to work unless they come out before my opponent gets the other one, and if I'm playing balanced, then I'm probably not going to win that race. So really it was between Burial and DoN, and I figured that there are a lot of ways to deal with artifacts (Captured Ark and Lying Unto God being 2 great ways). Therefore, it made the most sense to keep the dominant that I can't really replace with any other card (Burial). And since LS availability has become much more important, it just made sense to go with Burial to limit that more.
