Leadership can remove a condition by using Sneak Attack with Miner of the Iron Hills. Not entirely practical, since (with core set cards) you can't play it regularly.
Spirit can remove a condition by playing Miner of the Iron Hills with Stand and Fight. If you have Eowyn as one of your heroes, this can be practical.
(In the full card pool, Leadership and Spirit can both remove conditions, but Tactics cannot -- unless you count letting the hero be killed and then bringing him/her back with Landroval.)
