Im a relatively new player to agot but not new to ccg/lcg therefore i can play control relatively well. Just thought id post this deck and see what guys think.

I'd think about TVB as your restricted card instead of VB… with the lack of setup from KotHH you need as much draw as possible, and the extra gold from the Agenda makes their price more attractive. I'd also suggest taking out the Orphans - they are great for setup but don't look nearly as good in KotHH, especially when you have so little draw in the deck. I also think the Tourney Grounds suck, they are way too conditional, just personal opinion, others may disagree.
Twist of Fate is also very very dangerous, I have yet to see it work to the benefit of the person who played it except in a heavy control deck.
