Looking to improve my Muster Paladin deck.

Hi folks. Wanted to get some opinions on one of the decks I've been using for a while now with moderate to good success. I've been having a lot of fun playing it and working on it, but now I'd like to take it to the next level.

Since the TGT expansion, I've gotten lucky and pulled a Justicar out of one of the first packs I've gotten, and she's been nothing but amazing in it. I'm also considering swapping out some cards like Fencing Coach, but maybe can swap out some others if you think it could work out better in the long run.

I've gotten as high as 12 with it, but then get tossed backwards a bit. Kind of holding steady at about 12-14 with it, so any help on it would be awesome! This is the deck list Thanks for checking it out!
