It's a very risky and gimmicky strategy in fact. You may not have the time to do it. However, you could make it work in Doubles;
have the Victini along with a Amoonguss/Parasect/whatever gets Rage Powder or Follow Me.
Attack with V-Create then use Psych Up on your own teammate who will redirect attacks against it.
Now that's also pretty gimmicky but still. On paper it seems great, on practice it technically works BUT only if you're facing an opponent who gives you the time to do it properly.
