The main part of the power says, "Display this card to choose a character at your location to draw 2 cards from his deck."
Does this mean,
1) choose a character and that character draws 2 cards from his deck or
2) choose a character and you draw 2 cards from that character's deck?
They both seem to make sense when you are in a group discussing it
I am thinking 1) though as you "give" someone (any one at your location including yourself) a potion to drink which restores them.
