If your opponent blocks your attack responds with breaker, then reversals, will the breaker hit the block or will it float until you go to play another form. the reason I ask is because it was something that had come up during a tournament sunday, where it was said that "a block isn't played so breaker doesn't affect it" is that correct or does breaker hit blocks too?
