When using Nero, you'll sometimes wonder how far you can push the boundaries of his summons. Here's a trick that allows you to throw out TWO snakes, one after another, which is especially useful if you're on the other side of the screen and your opponent is trapped under an EX Deer.
Cast your first Snake(214) out. During the snake dropping, buffer the motion for your next Snake(214). As soon as the Snake finally drops out of Nero's coat, hit A or B for the 2nd Snake.
NOTE: You ARE allowed to throw TWO A.Snakes, if you hold [ A] for the 2nd Snake. Both A.Snakes will travel slowly along the ground until release.
This trick leads into the next one, A.Snake(214) -> A.Deer(421). With the same timing, do 214+A -> 421+[ A]. By holding [ A] for the Deer, you actually maintain the button for the Snake, because you are not required to hold [ A] until the Snake actually begins to travel along the ground. Sometimes, if your opponent blocks the A.Deer in midair, he'll fall right on top of your A.Snake, which you can release for another chance to hit. In ver.B, because Nero recovers even faster after the A.Deer, you may also have a chance to guardcrush your airborne opponent with a 5.B, and bounce them into the Snake!
I don't recommend using this trick in place of throwing out an EX Deer, but if you're low on Magic Circuit, it might come in handy to mix things up, especially if your opponent is used to the timing of EX Deer now.
