IT seems to have improved a bit. There are some cards you may want to consider removing for the sake of the deck:
1)
All is dust - destroys all COLORED permanents. That means your planeswalkers AND you creatures would hit the grave (but not your lands).
2)
Chandra Nalaar - if you swap her out for
Chandra ablaze then you can get more use out of the red spells that you draw and she can actually help trigger madness costs. For example, play
Chandra ablaze with
fiery temper and you can deal up to 7 points of damage!
3)
Dragon throne of Tarkir - if you don't play a lot of strong creatures it's not worth it. However, if you come across more
consuming aberration then it will create a
dangerous combo for any one to play against.
4)
Myojin of infinite rage - I wouldn't recommend this card. Destroying your mana base is not worth having an indestructible creature. You'd be better off with having zombies or creatures that keep coming back from the grave than putting a nuke into your field.
The rest of your creatures and other cards please add at least 2-3 copies of them all in any variation that you see fit. Reason being is that it'll help your deck's consistency and you'll be able to play more of your combos more often. Also decide whether you want to mill them and feed your aberration or
exile their graveyard. I'm seeing that the deck can swing both ways but it'll be more consistent for you if you choose one. This way your deck does not conflict with itself.
