So, basically I added Auriok Champions, more Serra Ascendants, another Ranger of Eos, another Cavern of Souls, and moved the Blood Moons to the side. I took Worship out of the sideboard, and Squadron Hawks/Blood Moons from the main to make room for the new cards.

Auriok Champion + Norin the Wary can get pretty annoying for most people, because most removal in this format is either black or red, and they both dodge Pyroclasm, Whipflare, and Anger of the Gods. It's almost unremovable, and so many people are running red (even Affinity runs 3-4 Galvanic Blasts) that they make value.

My deck is slightly different than the normal Norin the Wary lists for a number of reasons. One, I took out Mentor of the Meek. Not many people agree with that immediately, but in testing I found he was a dead card (literally dead) more often than he could make a huge difference. He'd get bolted or path'd or countered, and he didn't affect board state that much. Two, I only run two Purphoros because I think three is a little overkill. Three, I run four Norin the Wary instead of three, because I think that they pretty much always positively affect the board state, and if you stack the triggers well enough, you can do some silly things with multiple Norins. Four, and probably the biggest difference, is I cut Genesis Chamber completely. I found that Genesis Chamber was HORRIBLE against Affinity, because while you'd be gaining 12-15 life per turn, they would get infinite chump blockers and artifact count. Plus, without reliable trample (Legion Loyalist barely counts), the giant Ajani's Pridemates were more of a novelty than anything else.

Testing Results w/ changes (mostly on cockatrice, some paper):
2-0 vs Kiki Pod (Sisters stop Deceiver Exarch, and I have enough removal/sideboard hate to win G2 pretty easily)
2-1 vs UR Twin (Sisters and Path stop Exarch, Bolt stops Pestermite, but they sideboard pretty well against us with Anger of the Gods)
2-0 vs Tarmotwin (A good matchup in general. Lots of sideboard hate, too.)
1-2 vs Ad Nauseam (Regular Soul Sisters has a better matchup because Martyr of Sands can get out of range of Lightning Storm)
2-1 vs Melira Pod (Good sideboard against Pod)
2-0 vs Shamans (It's a fun budget deck to play against, but they have too many creatures that are beneficial to you, plus removal can stop most of their synergy)
2-1 vs Affinity (Game 1 sucks, and game 2 is just dead if you don't draw into sideboard hate. On top of that, you need to hope they don't draw Torpor Orb.)

Testing Results before changes:
1-1-1, 2-0, 2-1 vs UR Twin
1-2, 0-2, 2-1 vs Tarmotwin
2-1, 0-2, 1-2 vs Affinity
2-0 vs Scapeshift (easy to get out of range of the 6 land combo, and you can win before they go off generally)
2-0 vs Bloom Titan/Amulet of Vigor (you have 2-3 turns to build your board state for free)
2-1 vs Goblins (lots of creatures are pretty beneficial)
1-2, 0-2, 2-1, 2-0 vs Storm (really depends on the player and if the deck is fully complete with all fetches)
2-0 vs BG Rock (Lili can suck, but generally enough removal and sideboard options to win)
0-2, 0-2, 0-2, 1-2 vs BUG Infect (Just... not a good matchup)

So, thoughts? I'm thinking about maybe trying out Archetype of Aggression (my Pridemates and Champion of the Parish get huge enough that I think it's relevant). I also kind of considered going for RWb to run Bob and Thoughtseize (for more combo disruption). The mana base would be pretty difficult to build, though, and I'm worried it might not be reliable enough, so I haven't started playing around with it.
