Powerful

Have 10 or more buffs (positive Powers) active at once in a fight. Just pile on Power cards and buff effects in one combat - Strength, Dexterity, Focus, Metallicize, Demon Form, Barricade, Plated Armor, Vigor and so on each count. A Power-heavy Defect or Ironclad deck gets there, as does a Watcher with her stance/mantra powers. Play a long fight, keep dropping Powers, and you'll tick over 10.
