Guide to Pillaring
How to Pillar
Falco's Shine followed by a Wavedash into a full-jumped, double-jumped, or short-hopped ADA (L-Canceled), followed by another Shine into a Wavedash, into a full-jumped, double-jumped, or short-hopped ADA (L-canceled), et cetera, is called "Pillaring." Falco's Shine sends the opponent upwards, while his ADA spikes the opponent down. In effect, the opponent is sent up and down over and over again. This combo is usually finished with an aerial attack or an ADA spike off the edge.
Pillaring's Uses
Pillaring is used a lot in high-level play, and for a good reason. Pillaring can inflict heavy damage on fast fallers Fox, Falco, and Captain Falcon. It can also be used to destroy shields, as the ADA's lag time is very short when L-canceled, and the shine comes out extremely quickly, restricting the opponent's grab.
Technicalites
Of course, like other combos, Pillaring can be influenced by DI (Directional Influence). If one is not quick enough, one's opponent can escape this combo.
Strategies
Against Fox in particular, Pillaring is very effective. An example of how it would be used: Shine the Fox, Wavedash out of it quickly, then short-hop ADA the Fox, and repeat.
