Sensei's Divining Top + One with the Multiverse + Advanced Reconstruction

Sensei's Divining Top

One with the Multiverse

Advanced Reconstruction

How it works

1. Activate Sensei's Divining Top by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
2. Cast Sensei's Divining Top from the top of your library by paying 0.
3. Repeat

This elegant loop relies on the seamless synergy between Sensei's Divining Top and the top-deck permissions granted by One with the Multiverse, letting you tap the Top to draw a card and place it back on your library, only to immediately recast it for free. Advanced Reconstruction supercharges this interaction by utilizing its Level 3 ability to make spells cast from anywhere other than your hand—which includes casting the Top off your library—cost {2} less to cast. Because the Top costs {1} to activate, the cost reduction means you even generate a surplus of mana while churning through your entire deck, and its Level 2 ability tacks on lethal damage to each opponent every time a card leaves your graveyard to boot.
