I only use it if it's the final round and he's low on health and I've frozen him but he has a breaker and I have my x-ray. I'll hit the B2 reset, and then X-Ray. Opponent never has a chance to break when doing this.
thats what I meant with timing it, after the freeze I time the full B2 charge that it exactly hits once the opponent is unfrozen.. they cant jump or poke out of it
