As a goalie, it's not often you get to try and be a part of a trick play. What can you possibly do? You can't skate with the puck in your glove, you can't skate past the red line, and even goalies with the best puck handling skills aren't going to be able to weave around even the worst of skaters. So what's left? Well, while players aren't allowed to use a goaltender's unique stick, goalies are allowed to use a player's stick. Usually you'll see this when a goalie's stick breaks or is pushed far away from them in the middle of the play. So, in theory, a goalie could "lose" their stick, be given a player stick by a player on the ice, and then that player can go grab a spare from the bench. But how does that help? Wouldn't pulling the goalie for a sixth skater be more advantageous? 3 versus 3 overtime comes to mind. In overtime, if a team pulls their goalie, and ends up losing via an empty net goal, the team does not receive the "loser point". So it's dangerous to try and get an extra attacker. However, if the goalie were to instead use a player stick, they could assist in a 4 on 3 breakout and try to catch the other team off guard. You often see the attacking team intentionally leave the other team's zone in overtime to quickly regroup, and that's where I see this trick play being attempted.
