Delney, Streetwise Lookout

Oltec Matterweaver

Whitemane Lion

How it works

1. Cast Whitemane Lion by paying 1.
2. Oltec Matterweaver triggers twice, creating two copies of a Treasure token you control.
3. When Whitemane Lion enters the battlefield, it triggers twice, returning itself and another creature with mana value 2 or less that can be cast using colored mana from the battlefield to your hand.
4. If needed, activate a Treasure by tapping and sacrificing it, adding one mana of any color.
5. Repeat step 4 one additional time if you do not have enough mana to cast the other creature returned to your hand in step 3.
6. Cast the other creature returned to your hand in step 3 by paying its mana cost.
7. Oltec Matterweaver triggers twice, creating two copies of a Treasure token you control.
8. Activate two Treasures by tapping and sacrificing them, adding 1.
9. Repeat.

This ingenious little loop turns a humble feline into an engine for infinite value, entirely orchestrated by Delney, Streetwise Lookout and Oltec Matterweaver. Because Delney doubles any triggered ability of a creature with power 2 or less, casting Whitemane Lion causes Oltec Matterweaver to flood the board with duplicate triggers while the Lion itself bounces multiple targets back to your hand. You simply use the newly minted Treasure tokens to pay for the repeated casts, letting you churn out infinite artifact tokens, storm count, and triggers while keeping your mana entirely positive.
