Sensei's Divining Top + Traxos, Scourge of Kroog + Mystic Forge + Cryptolith Rite

Sensei's Divining Top

Traxos, Scourge of Kroog

Mystic Forge

Cryptolith Rite

How it works

1. Activate Traxos by tapping it, adding 1.
2. Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top on top of your library.
3. Cast Sensei's Divining Top from the top of your library by paying 1.
4. Traxos triggers, untapping itself.
5. Repeat.

This ingenious loop turns your library into an endless engine by pairing Mystic Forge with Sensei's Divining Top, allowing you to continually cast the Top straight from the top of your deck while looking right through it. To fuel this casting cost, Cryptolith Rite grants your creatures the ability to tap for mana, letting a resting Traxos, Scourge of Kroog pull double duty as a mana source. Every time you cast the artifact Top, Traxos's triggered ability sees a historic spell enter the stack and untaps itself in response, resetting the loop and letting you cycle the Top through your hand and library indefinitely.
