This is the Jinteki Fast Advance card, and it is only good if there is a place to bank those advancement tokens. Advanceable ICE for instance, is a great place to put them, and it helps relieve some of the tempo sting of advancing agendas. Scoring an agenda naturally requires time and money (clicks and credits), which means that every time the corp does so, tempo is being lost. Nothing is being done on that turn except setting up the chance to score, and if it is not fast advanced, then setting up the chance for the runner to steal as well.
Trick of Light alleviates some of that. Not only is it a Fast Advance strategy, allowing a three for two to be scored out in one turn (even a four for two), the process of putting tokens on advanceable ICE to save them for later spreads the tempo hit out over multiple turns to score an agenda, instead of all at once. It may not be the strongest of the Fast Advance core strategy cards, but it still has some uses and will still see play.
