Yea here is how I would play Sheik if I was going straight Zelda.zelda is one the the slowest characters in the game, sheik one of the fastest. You can bet if money is on the line zelda would never hit me espeacially on a large stage. conversely we can punish every attack she has spare jab and maybe dtilt out off sheild or just whiffed with dash attack which get zelda in the air which automatically puts her in a bad spot. space ftilt well in behind her and she has no strong answer out of shield, including bair.
love is invincible like frame 3 or 4? marth is invincible frame 1.
I don't know in my head it's just if zelda has to approach and she has horrible approaches all of witch sheik can easily punished and big advantages gained from then sheik has a big advantage in the match up as a whole.
obviously if you are trying to space bair and fair and tilts on zelda you are going to lose big to usmash and forward smash, so don't! play zelda weaknesses and punish her.
I strike FD. This forces the neutral to be on a small stage with platforms which Zelda ***** on. For Counterpicks I ban Halberd. What large stage are you going to be playing Zelda on?
Sure Sheik can punish most of Zelda's moveset. Not all of her moveset however and Sheik won't be kiling Zelda save a gimp until well after 100%. You always have to be aware as well that once your in that 70% range your in Zelda's KO range. Just one quick uair or bair and all of a sudden the match just got a lot more interesting.
