Counter Tips

You have to space out pikachu's neutral B and heavily readjust to your opponents playstyle like sort of camping with fair to block out neutra B. Using down or f tilt more than air attacks is good

i bet level 9 picachu spaming grab and shield. grab it then do some damage then move the movement stick down

Landing on top of pikachu with fast-falling nair and blocking his projectiles with fast-falling fair seem to work for me. The typical cross-stage combos you can do with speed shulk don't work as well.
