I posted another article on CardGameDB www.cardgamedb.com/index.php/index.html/_/game-of-thrones/game-of-thrones-strategy/how-to-build-martell-control-r31
This one offers some helpful hints for building Martell. Since Sato already published his Madrid Tourney deck list, I haven't spoiled those I use (but the outlines are the same, even if some card choices are different). This is more of a "how to" article than my previous article about Targ. Hope you enjoy!
