Sensei's Divining Top + Traxos, Scourge of Kroog + Elven Chorus + Experimental Frenzy

Sensei's Divining Top

Traxos, Scourge of Kroog

Elven Chorus

Experimental Frenzy

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 clever loop turns your topdeck into a self-sustaining engine by letting you repeatedly cycle Sensei's Divining Top right back to the top of your library to draw a card, then recast it using the mana generated by tapping Traxos, Scourge of Kroog for mana via Elven Chorus. Crucially, Experimental Frenzy gives you the ability to cast the Top directly from the top of your library while bypassing the restriction on your hand, all while its status as a historic spell neatly triggers Traxos to untap itself so the whole process can begin anew.
