One thing I noticed right away was the use of throws. Throws themselves are not bad, but in this matchup I'd say that if you get a throw with both ICs next to each other Fthrow is much better than Uthrow because it hits both of them , for example at around 2:22 you grabbed Nana and Uthrow and got punished by Popo for it. I think you need to use shines a lot more, especially running shines because they are so powerful in this matchup as well as shining to punish and kill of Nana. Like around 7:28 you approach with a nair that could be punished with CC from ICs, where if you had running shined at least one of them would be pushed off stage from it, and at around 3:56 you try to grab Nana then jab with Popo across the stage when you could have done shine->waveland onto platform and been in a better position to deal with both. I actually don't believe that Nair approaches as a whole are great because of the danger CC and instead almost exclusive do Drill, shine, and shield if I'm not platform camping. I would also say you could probably play a little more patience because platform camping ICs is really strong and from there you only have to worry them poking with Uairs which you can either maneuver around or just shield and shield drop punish it. Honestly this matchup is super hard to learn but once you do, the matchup becomes heavily in your favor, and you simply just have to find an IC and grind out the MU.
