I think Vizard Should be the SST in Lob and Arrancar the CS.
When you first obtain Vizard/Arrancar you are only able to use it for lets say 5 rounds?
You can increase the round by training your inner self.
Vaizards get a increase in attack and speed and also get the attack Cero
And the same goes for Arrancar, but maybe they could get a different attack.
