Basically trying to push your opponent to the wall by killing all their characters, forcing them to use valar if they have it. Since we have that technique, we have to perpare for it with dupes on dupes and plenty of bodyguard. Your power will come from renown mostly, with Tywin, The Mountain, Jaime, and Joffrey. The boy king will also work well grabbing power from all the kill going on. Eventually this is a war of attrition, as your opponent will soon have to kill off their larger characters, and even if they do valar, they will have no one to play, allowing unopposed challenges to flow easy. Insidious Scheme, lannisport, and Pycelle are your draw engine. Lions of the rock helps if you want to use trial, assassin or burned men while Tyrion isn't in play. Rebuilding will allow your to recycle bodyguards, trials, or schemes. Now to the kill. Double winds for double kill, with a trials and cersei = rage. Ser Payne can be a killer, literally, killing off claim soak. Queen's assassin is unexpected, while Gregor can hit a lucky high cost character off his pillage, while also target murder on the field. Widow's wail for an unexpected plus 2, as well as burned men, which can also claim soak if need be, Let me know what you think.
