With all you eldrazi, and other game ending high drops I think Tooth and Nail would be a nice addition, for 9 mana you can pick 2 op cards and just end the game... Also for when you get those high drops in your hand Scroll Rack can set it up nicely for Mayael to grab them, as can Worldly Tutor . Furthermore Austere Command and Bonfire of the Damned can act as a one sided wrath, and that is always good. Then for some good old commander hate Chaos Warp and Oblation do well to never see someones commander again. If you want some other ideas you could always look at my Mayael, the Chubby Chaser deck otherwise +1 for mayael

Thanks for the suggestions, I will certainly put Tooth and Nail into play and look into you other suggestions futher.

I have Scroll Rack just never found much use out of it initially, however I can always bring that back into play. I have been feeling that there may not be removal from my deck, sometimes a couple spell/enchants can trap me.

The best way to get rid of enchantments and artifacts is Aura Shards
