even though noel's chains seem like and endless, unstoppable combo, there's actually a lot of holes in it. though it takes practice, when you're blocking and they're moving on to the next move in their drive, there's openings for you to do a 5B. You can't do it in between any of the drive moves, but experiment and you'll find the ones that you can. When you land that 5B, you can do a 3C, to a drive loop if you get all 3 hits. If you don't think you'll get all 3 hits in the 3c, you can do a forward drive with a B cancel after the 2nd of 3 hits to land on the other side for a mixup, do another 5B, 3c (3 hits) to a drive loop and be a happy camper again.
in the other case when noel is doing the low drive moves 'cause you're blocking low a lot, you can do a 6B and that's the little flippy kick thing to go over the low drive move, do a 2A to a 3C and drive loop that way instead.
if you're REALLY good with your timing, you can do a 4b+c to do a back throw, 236C and drive loop. i don't recommend this 'cause you have to be really close to noel and if you're blocking a lot you might not get that close.
