teleport is also really important in matchups where single projectiles get shot at you quickly (green arrow comes to mind). The ending frames have invincibility for 1 projectile hit. You'll get blown up if you spam it yourself, but it does get you past some really irritating zoning.
It also mixes up your 'block -> dash' timing so stuff that's designed to frame-trap your dash will miss.
