Sensei's Divining Top + Experimental Frenzy + Bilbo, Thief in the Night

Sensei's Divining Top

Experimental Frenzy

Bilbo, Thief in the Night

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 clever setup turns a simple artifact into an engine of endless card draw, fueled by the top-deck permissions of Experimental Frenzy and the crucial cost reduction provided by Bilbo, Thief in the Night. Because Bilbo makes spells cast from anywhere other than your hand cost {1} less, Sensei's Divining Top becomes completely free to cast from the top of your library. When you tap Sensei's Divining Top to draw a card and place itself back on top, Experimental Frenzy lets you immediately recast it for zero mana to repeat the loop indefinitely.
