Explanation: Cast Ghostly Flicker, targeting Mnemonic Wall and Peregrine Drake. Wall returns the Flicker to your hand, and Drake untaps more mana than the Flicker costs, so you can float infinite mana doing this.
With the infinite mana, you can start Flickering the Wall plus something else infinite times. Mulldrifter or Prophetic Prism to draw your whole deck.
Can also use Cloud of Faeries if you have bouncelands.
