It's up to you! Some nicely timed explosions would be just the trick to pull attention away from the group sneaking in, but Clint's shadow powers would also work well, not to mention that would make 3 broodmates working together, so they might be more effective.

If Clint joins team infiltration it'll be a fourth person, which Bruce will definitely be against bringing any more because they're already pushing the stealth boundary, so that would have to be the limit and be therefore the official team.

BASICALLY AN UNHELPFUL RESPONSE I'M SORRY, which would you prefer?
