Basically, this is a new desynch that allows you to do some pretty funky stuff out of a run.
Statements which are important:
You can do any special move during a run with no lag.
You cannot do any special moves during a dash animation.
Nana has an 8 frame delay with popo for execution of inputs.
You can reverse momentum during a b move on the ground in the same way as in the air.
Ice block to grab is awesome.
If you begin a synched dash animation, and popo is near the point of starting his run animation, and you press B, popo will continue on dashing forward. The input is then transferred to nana, 8 frames later. If anywhere during that time she enters her run animation, then she is able to do an ice block while popo continues on running. This leads to them being desynched, as long as the ice block was inputted before popo enters runs animation but within 8 frames of nana entering it. You can also do any specials instead of ice block. This is the first use of the desynch. You can now desynch out of any dash while still moving forward with popo which can result in a free grab.
Experiment with it to find the best comboes, going from ice block to grab to blizz to side b.
2nd important use of this, the counter ice block. Instead of dashing towards the ennemy, dash away. Use the ice block as usual to desynch them, but then reverse it quickly by pressing towards the ennemy. Nana will reverse momentum.... BUT SO WILL POPO! I have yet to find any reason as to why this happens, but it allows you to get in surprise grabs very easily. Its a true ice block to grab combo because popo runs in the ice block.
3rd use is that if you are running towards the ledge, and shield at the right time to cancel a dash, then restart dashing towards the ledge, do the desynch. As usual, popo will run towards the ledge but not fall(you arent holding towards it anymore, he will just get as close as he can). On the other hand, nana will fall due to the ice block momentum, thus leading to nana being alone onto the ledge. This is a very advantageous situation vs alot of characters(save MK/ROB/recovery freaks) where nana can fair onto the ledge and spike while you fsmash, or any type of combo of the same type.
Basically, this is a surprise grab and counter effects, which is awesome. Add in more ledge games options make this even better. Also, +1 for unpredictability and comboing near the ground.
I sense a new triangle forming.
