Jynx

Explanation
Magic guard allows Jynx to switch in multiple times when stealth rocks are up, tank toxics and burns and still set up substitutes or breaking its potential sash. Alongside this new ability, the buffs to hail allow it to fire off 100% accurate blizzards at the opponent.

Abilities
Forewarn: No changes

Dry Skin: No Changes

Magic Guard: This will probably be Jynx's main ability. It gives it an immunity to passive damage of any sort, including stealth rocks.
