Skellige Bran Deck, any feedback?

Deck: http://www.gwentdb.com/decks/22288-bran-bran

So I am pretty new to Gwent, just hit rank 11 or 12 and have not yet played in competitive. I have been fine tuning a Skellige deck (I dont run bears and do fine against others bears) and it seems to do well against most decks in casual (even the cookie cutter decks that I have seen mentioned on this sub). I am still getting my "bearings" here, so I am sorry if this is already a deck or has already been mentioned.

The only decks in casual I have started seeing that cause problems are certain machine decks and the occasional Nilfgaard or Scoia'tael if they are able to put out a big resilient bastard at the right time (as long as its not over 15-20 power its usually not a large concern).

I am gearing up to start ranked play and wonder what you guys think given your knowledge of the MMR brackets and what is played most. I mainly focus on winning the second and third round, with a strong second and third round finish or a strong second round followed by a card advantage win in the third.

Draw/Mulligan: Always ditch raiders, you want them in your deck. I never really play them from my hand if I can help it. The rest I dump based on my current hand composition (extra amorsmiths, etc).

Depending on what I am playing against, I will try and bait the opponent into over extending with a first turn Bran, dumping either all 3 Craite Raiders or sometimes 2 raidders and Morkvarg/Olgierd. I then focus on card advantage and have no problems dropping the first game on them when they are half way through their combo, or if I have a big lead second/third turn depending on their first card played. Sometimes its best just to play more passive though and save Bran. So far it seems this deck does well either way. (Also, I just added Champion of Champions in hopes of stronger first games. In the limited testing I have done it seems to give the deck a bit more oomf in the first game.)

Game 2 and 3 I do my best to control what I can on the board and lay out fatties. By game 3 my pirate captains are usually 10-12 power each, and I save any golds possible for the last stretch. While Birna Bran can be shut down sometimes, that card is a beast and I love the shit out of it. Ermion works out well (if even still a little underpowered) for dumping more against your pirate captains or just cycling cards 2nd and third round you do not need. The 1 berserker has come in pretty handy in the later rounds against weather effects, random damage, etc.

So, what do you guys think? Thank you for reading and your feedback! =)

Edit: I have also run Renew and it works well but the deck has changed a lot since, may try and squeeze it back in.
