Paulo is correct. I'll just add the relevant language from the rulebook (page 10):When you take the maneuver action, you may boost your movement. To do this, discard 1 card from your hand and add that card’s BOOST value to your movement value. Ignore any effect on the discarded card.
Certain effects (like King Arthur’s special ability) allow you to boost other things, such as the value of an attack.
Cards that can no longer legally be played — because the corresponding fighter or fighters have been defeated — may still be discarded from your hand to boost.
