It is not that plus on block. That is not what makes it good. The Artillery Strike forces them to block which means you are allowed to go in with pressure.
There are times in this video where you are allowing the opponent to attack. Once you do Artillery strike you immediately rush in and do the follow up. You don't wait. That is where the read comes into play to see if they will wake up or not. If you read they wont wakeup you go in immediately. It doesn't matter if you are plus on block or not. The thing that makes it good is that they are forced to block which means you are free to rush in with pressure. I played the last two days with this and labbed again and every thing in my original post is legit.
I will be working on corner setups today because I think I have found more stuff.
