How is this card used?
It s a territory class enhancement, meaning that it can be played during the prep or discard phases on a character of matching brigade in territory, or used normally in battle. It is a fantastic card that lets you get an evil card from your deck, which makes it useful in battle, but that is honestly not where it gets used most of the time. Mainly, it lets you do mean things like put all your souls on the bottom of your deck, and get less useful cards off the top or set up your next draw for the cards you really need (like a dominant).
