Trusty Boomerang + Mana Echoes + Tuktuk Rubblefort + Barret, Avalanche Leader

Trusty Boomerang

Mana Echoes

Tuktuk Rubblefort

Barret, Avalanche Leader

How it works

1. Cast Trusty Boomerang by paying 1.
2. When Trusty Boomerang enters, Barret's triggers, creating a 2/2 Rebel creature token.
3. When the Rebel enters, Mana Echoes triggers, adding C for each Rebel you control.
4. Activate Trusty Boomerang's equip ability by paying 1, attaching it to the Rebel token.
5. Activate the Rebel by paying 1 and tapping it, tapping a creature and returning Trusty Boomerang from the battlefield to your hand.
6. Repeat.

This clever loop turns the steady equipment synergy of Barret, Avalanche Leader into an endless factory of rebels and colorless mana. Every time you cast Trusty Boomerang, Barret answers by forging a 2/2 Rebel token, which immediately supercharges Mana Echoes to yield a surplus of colorless energy upon arrival. Tuktuk Rubblefort ensures your newly minted tokens are ready to act instantly, allowing you to pay the activation cost of the boomerang's ability—or bounce it back to your hand via its own text while tapping down an adversary—to sustain the cycle indefinitely.
