For noob saibot, if you end your combo with 214 slide, an ice blast will beat all of his wakeups, you just have to time it. its fairly simple. The worst tht can happen is he trades with you, and you can still then get up and 214 slide, resetting the situation. Im not entirely sure if it works off of 212 slide, at least the same timing will not work due to the slight change in spacing.
