Press B 3 times and you are in jump (double tapping quickly cancels your current art) or press B 4 times (if you aren't comfortable with the double tap). You can basically do this in 1 second, then its 1s for the art to take over.
When Im on my A-game (not now cus im in a funk) Im almost immediately in jump.
Jump is basically you're main edge-guard, maybe smash sometimes. I've gone for the edge-guard in speed too many times....and ended up falling WAAAAY too quickly.
Honestly my shield useage despite me loving it before is declining. If anything I use Shield to get them to 30% or so when Im high% and then its switch to Buster, or Speed and im going aggressive on that ass, unless it's one of those match-ups where they're retardedly fast in their attack speed and animations... (why hello thar Sheik/Fox) then yeah Shield tank it is.
Im just trying to get into my mo-jo with Smash. I used to use it a lot, then I realized how *easily* it makes it to kill you. Then I realized how much of a pain it is to kill things outside of Smash...
If I were to analyze it best.
Buster's low damage modifier (shields as well) also translates into a lack of hit-stun. Because of this speed and Vanilla are to me often good starters, though speed also has a damage penalty. Once a little damage is racked up, basically buster's "stun" is equivalent to what speeds used to be, so Buster starts becoming better than speed for strings.
