Works similar to up b out of shield, but if someone dash attacks the back of your shield nair is a very quick/good option. It hits any character at any length. Up b out of a shield makes you more vunerable and you lack follow-ups, even though it does have an advantage of four extrama damage. Just be sure to SHFFL the nair if you use it out of a shield so its much quicker. Nair is situational OOS because it there are better options if you have a banana in your hand out of a shield than that of course. Just throwing this out there, bair and fair work very well as well occasionally. I love bair out of shield <3333
