By pairing **Teferi's Puzzle Box** with **Spirit of the Labyrinth**, you turn every draw step into a devastating trap that strips your opponents of their options. Normally, the Puzzle Box forces players to bottom their hands and redraw a fresh mitt, but **Spirit of the Labyrinth** acts as a hard restriction that caps everyone at drawing just a single card each turn. Because the active player has already drawn their mandatory card for the turn before the Puzzle Box's trigger resolves, the restriction kicks in and leaves them drawing nothing at all while everyone else merely replaces their single card, completely locking your opponents out of building a hand.
