This clever loop turns your topdeck into an endless engine by weaving together cost reduction, draw effects, and library manipulation. Voyager Quickwelder does the heavy lifting up front by making Sensei's Divining Top completely free to cast, while Skyswimmer Koi rewards that entrance by triggering a draw and discard. Before that draw trigger resolves, you simply tap Sensei's Divining Top to draw a card and place itself right back on top of your library, ensuring the Koi's effect scoops it right back into your hand instead. By repeating this dance, you churn through your deck with infinite lootings and draw triggers, filling your graveyard and running up your storm count to incredible heights.
