Well met. I also play a midrange pally deck. Looks like you have a little bit of a inspire theme going on. Are you liking Maiden of the Lake? That is not a card I would have considered. I would probably go with a Justicar if you are wanting all the inspire value. A one of Mukla's Champion late game can get really out of hand buffing your whole team. Surprised you are not running a Lay on Hands. That card has turned around many a game for me. You might consider a one of Blessing of Kings. Goes really well on a divine shielded minion. If you are having any face cancer problems you could add a Defender of Argus. I am also a big fan of Aldor Peacekeeper. I would run more than two if i could. Nothing better than essentially nerfing your opponents big threat and then ignoring it. Nice 1/7 Dr you got there. Another consideration is a Loatheb. Card is great against the combo decks. Just need to play it at the right time, and can close out the game for you.
Hope that helps.
