Sensei's Divining Top + Mystic Forge + Temur Battlecrier

Sensei's Divining Top

Mystic Forge

Temur Battlecrier

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 loop turns a simple artifact into an endless engine, fueled by Mystic Forge allowing you to cast Sensei's Divining Top directly from the top of your library for free. Once you tap Sensei's Divining Top to draw a card and place it back atop your library, Mystic Forge lets you immediately replay it for its zero-mana cost—a loop you can repeat as many times as you like to draw your entire deck and rack up a massive storm count. Meanwhile, Temur Battlecrier sits on the board ready to slash the costs of your other spells if you happen to control large threats, though the core of the engine relies on the endless synergy between the artifact's top-deck dance and the Forge's top-of-library casting permission.
