Sensei's Divining Top + Elsha of the Infinite + Semblance Anvil

Sensei's Divining Top

Elsha of the Infinite

Semblance Anvil

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. Elsha's prowess ability triggers, giving it +1/+1 until end of turn.
4. Repeat

This clever setup turns a modest artifact into an endless engine by altering the fundamental math of casting spells. With Semblance Anvil already having exiled an artifact to reduce artifact spell costs by {2}, Sensei's Divining Top now costs zero mana to cast rather than one. Meanwhile, Elsha of the Infinite quietly anchors the entire operation from the battlefield, granting you the crucial ability to look at and cast noncreature spells directly from the top of your library. You simply tap Sensei's Divining Top to draw a card and place it back on top of your library, immediately recast it for free thanks to the Anvil's cost reduction, and repeat the loop to draw your entire deck while pumping Elsha's prowess trigger to astronomical heights.
