you probably wanna run more than 4 mana guys, and less than 3 solemns, solemn is great, don't get me wrong, but it feels like he doesn't do enough most of the time. Arc Trail seems like its where you wanna be right now, while Dismember seems like it is not. It could be in the side board for infect if you would like though. I would replace it with more arctrails, or galvanic blasts or something. And wolf run is a different monster than valukut, not only are you afraid of their late game, you are afraid of them all the time since Ancient Grudge is a card. I personally run blue in my pods so I can board out pods and board in counterspells and just play control. perilous myrs should not be your plan for mirran crusaders cause you can just zap them, but if you feel you need them for phyrexian ones, thats a different story. also, I don't really see a side board plan for aggroe, I see hollowhenge, and thats actually not very good in my past experience with pod. if you run white, not only does timely come out faster, it also gains you more life. What are you having in mind with the Naturalize but not Ancient Grudge? The only playable enchantments I can think of off the top of my head are Angelic Destiny, and Tempered Steel. One you just just burn the target unless its geist, and the other you could just throw in more ancient grudges.
