-Tap the top to draw a card -Before you put the top on top of the deck, activate Voltaic Key to untap the top By doing this you get to draw a card for 1 colorless mana and it can be done every turn for as many key's as you have. It makes for a good draw engine with Brainstorm, then you are constantly weeding through the top deck and drawing cards.
