Lannister Crossing

I live in Brazil and here in my city we have a melee tournament every month and I won my first tournament with this deck.
I was trying to find a good Lannister deck... althought the Lions are very good in joust, I don't think they are that great in melee.
There were 12 players and I won three of the four rounds. On the last round I finished in second. No match ended by time.
The cards allowed were core set and the first three chapters of the first pack. Now, I'll have to modify the deck with cards of the last three chapters of the first pack and the Wolves of The North cards.
I would really appreciate any suggestions. I know there are few players that like melee tournaments.

The first plot is calm over westeros and the claim you must choose is military. Try to marshal Tywin or Clegane (with a noble lineage). You will need the reknown.
Then, slow the game with a game of thrones. Do not choose Crown Regent. You are going to need the bonus from rivals, since this deck is slower than Greyjoy and Tyrell rush decks.
Power behind the throne will be very important, because at this point you are going to make two conflicts with the same character, Tywin or Clegane or even Jaime.
Jaime, by the way, is amazing with Lords of the crossing.
Another character that must be marshalled early in the game is Joffrey.
If everything goes wrong, on the second round you will play noble cause or calling the banners if you need gold, summons, if you really don't have Tywin, Jaime or Gregor.
