Sneak Attack + Wizard Mentor + Priest of Gix + Skyshroud Elf

Sneak Attack

Wizard Mentor

Priest of Gix

Skyshroud Elf

How it works

1. Activate Sneak Attack by paying , putting Priest of Gix from your hand onto the battlefield and giving it haste.
2. When Priest of Gix enters the battlefield, it triggers, adding .
3. Activate Skyshroud Elf's second ability twice by paying 2, adding .
4. Activate Sneak Attack by paying , putting Wizard Mentor from your hand onto the battlefield and giving it haste.
5. Activate Wizard Mentor by tapping it, returning it and Priest of Gix from the battlefield to your hand.
6. Repeat.

This clever loop relies on Sneak Attack to cheat creatures directly into play from your hand at a moment's notice, letting you deploy Priest of Gix to immediately harvest three black mana upon arrival. You can then use Skyshroud Elf's flexible ability to filter that black mana into the red resources needed to keep Sneak Attack firing. Finally, Wizard Mentor steps in as the bounce engine, tapping to scoop both itself and the Priest back to your hand so the whole cycle can begin anew with infinite profit.
