Dockside Extortionist + Wizard Mentor + Lightning Greaves

Dockside Extortionist

Wizard Mentor

Lightning Greaves

How it works

1. Cast Dockside Extortionist by paying 1.
2. When Dockside Extortionist enters the battlefield, it triggers, creating at least five Treasure artifact tokens.
3. Activate five Treasures by tapping and sacrificing them, adding 3.
4. Cast Wizard Mentor by paying 2.
5. Activate Lightning Greaves' equip ability by paying 0, attaching it to Wizard Mentor.
6. Activate Wizard Mentor by tapping it, returning it and Dockside Extortionist to your hand from the battlefield.
7. Repeat.
8. If opponents control at least six artifacts and/or enchantments, this combo nets infinite Treasure tokens.

This loop turns the artifact-counting potential of Dockside Extortionist into a self-sustaining engine by utilizing Wizard Mentor's tap ability to return both itself and the Goblin to your hand. Lightning Greaves plays a crucial role by granting shroud for zero mana, though you will need to unequip or reassign it carefully during the sequence since Wizard Mentor targets itself and another creature you control. As long as your opponents control at least six total artifacts and enchantments, the Treasures generated will more than pay to recast everything, netting you an endless parade of enter-the-battlefield triggers and boundless mana.
