My Keranos list is a pretty straight forward u/r spells list. I utilize reset/reiterate/bolt and Teferi/Possibility Storm as the traditional win-cons. My meta is Ezuri elfball, a very tuned Roon list that can lock the table down in a multitude of ways, Marchesa, Purphorous, Kozilek, Ezuri CoP, Meren Stax, Krenko and Oona. Every list is pretty finely tuned but Kozilek Purphorous Roon and Marchesa are probably the strongest decks. I am looking to fine tune the list, I am not on a specific budget and cards will be acquired over time. Volcanic Island and Tarn are already on the need to get list.

So that is my Keranos list, I have been running it for a few months now slowly taking pieces out that just weren't working. I have gotten it to a point where I feel like it plays very well. The amount of CA generated is fantastic sometimes getting you to see 12-13 cards a turn. I am looking for some constructive editions that maybe I overlooked or just plain don't know about.

It's a midrange deck built to get Sidisi out and exploit so you can get Silumgar in play, two big body deathtouch creatures to turn the tide with plenty of removal. Just trying to get a feel for what's sub-par in the deck. Thanks for your help.
