If I have Suicune with the "Wind Charm" Ability Active and my opponent attacks with Greninja's "Shadow Stitching", are all my Abilities turned off including "Wind Charm", or does "Wind Charm" prevent "Shadow Stitching" from disabling my Pokemon's Abilities?
Wind Charm prevents Shadow Stitching from disabling your Pokemon's Abilities. However, if Suicune goes to the Bench, Wind Charm's effect goes away and your Pokemon will no longer have Abilities that turn. Suicune also does not protect any Pokemon not already in play.
