This clever engine turns Sensei's Divining Top into a self-sustaining loop by leveraging continuous cost reductions and top-deck manipulation. With Fortune Teller's Talent at Level 3 and Gran-Gran's passive cost reduction active, the mana cost to cast Sensei's Divining Top from the top of your library is entirely eliminated. You simply tap Sensei's Divining Top to draw a card and place it back on your library, cast it for free thanks to Fortune Teller's Talent letting you play from the top, and repeat the process. Along the way, Gran-Gran's loot trigger helps churn through your deck while you rack up an endless storm count and draw your entire library.
