Does the ability sweet veil have any effect when the user is not battling in doubles, but is in the party?

I was wondering if sweet veil still activates even if the Pokémon with the ability hasn’t been sent out to battle yet. By this, I am referring to not sending it out in double battles, but rather waiting to be sent out. This is during competitive play. I was curious before adding a Slurpuff to my team.

Sorry for the confusion before correcting my question.

With some research, I’ve concluded that, unfortunately, the ability Sweet Veil doesn’t have an effect when the Pokémon is waiting to be sent to battle. Sorry about that. It only works on itself in single battles, or its allies in double or triple battles, and only takes affect when the Pokémon is on the field directly. If it is not on the field, Sweet Veil will not be activated.

It also doesn’t have a affect completely outside of battle.

Hope I helped! Also, I think rephrased the answer slightly, to better answer the question provided. If it still isn’t answering it though, please let me know, and I’ll rather do more research or hide this answer.
