Thanks.
I used to sideboard out Memnite all the time, but it's actually pretty fast with Drum and helps me cast my sb cards faster. Believe it or not, Master of Etherium is my most sided-out card against the top decks.

Underground River - Darksteel Citadel is great, but I need more access to :u: and :b: without cutting Cities. I figure 1 Underground River is a good enough tweak without weaking Affinity for Artifacts significantly. Note I'm not using
Glimmervoid because I only need access to :ub: and I don't want to lose Glimmervoid if I get hit with a Pernicious Deed. EDIT(2): Obviously, I'm not running
Underground Sea because it is an Island, and Merfolk is back in the scene.
Arcbound Ravager - You might want to wait before you yell "I told you so!" I still think Ravager + Disciple isn't worth it, because Disciple requires too much setup and is too situational. Also, I only argued there are better creatures to run than Ravager, such as Etched Champion. With the exception of MoE, I believe all of my creatures are better than Ravager. However, I've been really disappointed with Master of Etherium lately. It's been screwing up my opening hands where I don't have access to :u: and moreover it loses me a lot of tempo when it's removed by my opponent. After having some lingering thoughts for a while on the possibilty of using Ravager + Vault Skirge and seeing the synergy between the two firsthand through losing g2 and g3 to Kanti on MWS (it's a small cyberworld after all!) I think I could at least try Ravager for myself. But I'm only testing 1 and by default it's already competing with MoE for the slot of 'worst post-sb creature' in my deck so it has a lot to prove.
Etched Champion - Not much needs to be said, other than the reason I moved the 4th Champ to the sb was to make room for the 3rd MD Vault Skirge. I still need 4 Champs in my 75, so I cut the 4th Pierce for it.
