Quote from ClopClop »Hey I skimmed the forum and didn't see any talk on mox opal. The addition would force you to most likely increase dark steel citadel to 4 copies, but in theory it could speed the deck up.
Also, what about monastery mentor? He is very slow for what this deck is trying to do, but he would help with removal spell weakness of the deck and could easily end the game if you I tap with him. The tokens also work nicely with mortar pod.
I have no experience with the deck, just some thoughts
