I haven't tested this at all, but Markatas could be useful if you're using Rust Mist heavily. Removing the protection of a unit makes any hits they score likely to do a little bit of damage, and since they're very small they can swarm units causing them to accure defense penalties, especially against larger opponents, and the damage could add up quickly (if they don't all die first). Ideally I think that Rust Mist is best used with high strength units though, but it might work.
