Quote from benjameenbear »While he's normally a pretty useless card, I actually think that Padeem, Consul of Innovation could be a worthwhile inclusion. Giving your artifacts Hexproof seems really solid.
Also, is there any reason you chose not to use Sharuum as the Commander? Having a guaranteed way to recur the Citadel or any other cards that get discarded/destroyed/Wheeled seems too good to pass up, along with the typical Sharuum combo lines. Overall, it seems like Sharuum might be better for your overall strategy? I certainly recognize the power of Tymna in the Command zone though, so I can definitely respect that.
Quote from benjameenbear »I think that this is a really cool idea, actually. Have you considered Kambal? I can't remember the full card name, but it gains you life every time an opponent casts a non-creature spell. It would be a great way to pad your life total over the course of a game so that you can truly abuse Bolas' Citadel.
