You could also consider Hans, to shoot off Sub-Zero (which can mess with a melee-oriented crew such as yours) or even get rid of Shattered Heart, which limits Raspy's casting. Even the threat of losing either of these two upgrades could cause the Raspy player to play more defensively.
10T Archers are ideal, however, as they can Rapid Fire into the melee Mei Feng and Kang have created and ensure they will not hit friendlies.
A melee crew dealing with a ranged crew might not be best suited to adding generic ranged support however, since you cannot really compete with the enemy in ranged damage output and might hit your own guys.

You can unbury the Raptor in melee with Raspy at the end of the Turn
