The basic schtick of this deck is to just play a fully activated Champion of Order. That’s it. Press the Advantage is there to be a cheap Aegis outlet for a 6-power combo with Chord.
The deck isn’t close to perfect at all, but I feel like the win condition of the deck is very doable and currently is unexplored in Expedition.
