Drop the 10 knights, they'll screw you with weather along with being in 1st position with your Impera Brigade.
You need standard bearers. They're 100% mandatory. I'd put in two.
I'd drop the bear, and add two engineers. The ability to add Resilience to any beefed up units you have makes a HUUUUUGE difference. Even if you just nab a 6 catapult with Resilience, it's often a game-winner. Optimally, you'll want to use it on the unit that gets summoned by Joachim or beefed by Ambassador.
Renew is also questionable. Geralt:Igni works well against SK players as they usually carry more than 20 in a row in rounds 2 or 3. But, he's situational, so it's up to you. I've used Letho in spy mode, bombed him, then used Igni to destroy him. Upset people... rofl
You might even drop down to 2 Catapults and add another Medic or even a Spy. Never had much mileage to absolutely utilize 3 of them.
Auckes is a must. I can't see playing NF without him.
I also prefer Emhyr Var Emreis for leader. The bounce is priceless, especially if you're playing against SK and bounce your Medic for round 2. Remember, you can bounce a card and play a different one if you choose. If you go with Emhyr, you can drop Decoy and slot in Auckes. You could also drop bomb and go with Shackles (bronze) to free up a Silver.
I even like Golem. It's a 10 power meat monster that denies opponents cards in rounds 2 and 3. If they mulligan those cards back, it later screws with any Rally that they cast.
