There is no prep. They start in the situation with standard gear. What is standard gear for Batman? Explosive batarangs, regular batarangs, gas pellets, things like that, whereas Black Panther is armed with a vibranium suit, anti-matter claws or whatever the hell they're called, an energy dagger and any other standard gear he carries. I'd say T'Challa has the edge on the equipment front; it'll be much more useful when handling undead ninjas, and it doesn't eventually run out.
EDIT: Reading the above conversation about what does and doesn't kill Hand ninjas, I've seen them get hit across the face with billy clubs, sai handles, and even kicked, and they fall to the ground and dissolve. Whether their necks had been broken or something, I dunno. But it means that any bladed object is going to slice 'em like butter, giving Logan advantage.
