I disagree. I think PG is the best punishment because it will lead to one less stock. fsmash is easy to bait and punish the end lag. PG is much harder to bait safely because you have to tornado towards them for them to attempt it, which can end up getting you grabbed if you dont space it perfectly.
I think shielding is better than fsmash if they are too high to pivot grab. They will generally have to run away near the end and that leads to upairs through platforms or a safe desync.
If they dont end up on a platform pay attention to what they do after the tornado, if you run towards them and try to grab 9/10 they will be able to spotdodge it and hit you. If they do this it makes for an easy grab because you can just wait for the spotdodge and grab them in the end lag.
IC can't pivot grab the nado if MK does it well, it doesn't need to be perfectly spaced and it's quite possible to do this consistently. MK should always go to a platform after performing tornado, and they should always start pulling back once IC block it, so they should be too far away to be Uaired. MK should usually back dash if he doesn't end on a platform, it's safer and doesn't get punished like a spot-dodge is. Blocking a MT does give IC a chance to desynch though, that's true. If they don't have a lot of shield left, they can get shield-poked though, I think.
Also, Uair will only hit MK if they're stupid and challenge the move head on.
At the person saying you should solo climber chain-grab until 60% and then start the chain: If it's all you attempt to do, you may end up losing stocks before you do much damage, only because you want to secure a chain-grab by trying to keep MK at very low %.
PS: I can beat bad MK players as IC the easiest. It's 5/5 IC if the MK doesn't know the match-up. Plus the opponent being worse, makes it like 7/3 my favor (or even better)...still, like I said, I haven't seen a MK player play the match-up as they should.
From my experience playing MK players that don't know the match-up, I can say I do this:
- Wait for mach tornadoes to pivot grab them
- Run below them and Uair them when they're in the air, if I performed SH uair and they air-dodge through, I can nair or bair them before IC reach the ground
- Desynched blizzards when they're in front + desynched Uairs when they're above seems safe, although I think they can sneak Mach Tornadoes in and maybe other things.
