Pushblock) like in the concept 1 is great because it is a 50/50 with your whole lifebar at stake, you need to guess which way to block the j1 first, and then pushblock immediately, then backdash to avoid the freeze. Second one is easy, just pushblock as soon as you can block.
This character has guaranteed resets midscreen for 2 bars ( where you can't pushblock or backdash) which do 700+ damage, I have posted an example of such reset in Cold's general discussion and in the media section. And for one bar there has always been a reset, that I think Red Raptor posted long time ago, where all you can do is time the pushblock so that it happens at the same time as the freeze from the globe, mistime a couple of frames and you are eating 700+
