Something that I have personally come to love to do during practice is one time shots on the boards with a partner.
What you need to do to be able to do this is have a partner and a couple of rings. Stand about a crease length apart and one person passes the rings while the other stabs the ring and shoots it as quickly as possible. Switch up who is passing and shooting and also be sure to shoot and pass from both your forehand and backhand.
This really helps for in games when you get one of those one time passes.
