This delightful loop turns your library into your hand by exploiting a clever interaction between top-deck manipulation and cost reduction. With Jhoira's Familiar discounting historic spells by {1}, Sensei's Divining Top becomes completely free to cast. You can tap the Top to draw a card and place it on top of your library, and because The Lunar Whale lets you look at the top card of your library at any time, you always know when your artifact is waiting there to be cast again. Repeating this cycle allows you to draw your entire deck, rack up an arbitrary storm count, and trigger any number of draw-based effects at zero mana cost.
