In a Shelters game, Way of the Mole could potentially allow you to play a card on turn 2 that you gained on turn 1, if your Necropolis is drawn on turn 2. Buy a card on turn 1. Turn 2, play Necropolis with Way of the Mole. Discard your hand and draw 3 cards. Since this triggers a reshuffle, you have a 30% chance of drawing the card you bought on turn 1. Especially useful in 5/2 openings, where you'd probably want to use Way of the Mole anyways, unless there's a good $2 card. Even if you don't draw what you'd bought, you still have a good chance of getting 3 coppers with your draw
