Although the fights already biased seeing as how we have Tony's feats with this being his fourth appearance in the MCU displaying fighting skills I could see him quickly pull in off that sweet analyzing move he did with cap on BP. This unfortunately wouldn't help him though cause we see how although T'challa's first appearance in the MCU we see that his suit aren't affected by bullets from I think a machine gun. And he was able to scratch up Caps' shield. The ironman armor has no chance
Bullets from a machine gun are all good until you remember Iron man armor brushing off a tank shell in stride as well as Mjolnir. BP was still getting hurt by Cap and Bucky's attacks just fine. His piercing damage is great but he didn't display any blunt force durability that was too great for either of those 2. The claws are probably his only chance but I don't see Panther doing enough damage before Tony analyzes him.
