Sneak Attack
Core Set#23 (x2)

Action: Put 1 ally card into play from your hand. At the end of the phase, if that ally is still in play, return it to your hand.

There is a seed of courage hidden (often deeply, it is true) in the heart of the fattest and most timid hobbit, waiting for some final and desperate danger to make it grow.
