Trusty Boomerang + Mana Echoes + Chishiro, the Shattered Blade + Tannuk, Steadfast Second

Trusty Boomerang

Mana Echoes

Chishiro, the Shattered Blade

Tannuk, Steadfast Second

How it works

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

This clever loop spins entirely around the synergy between Chishiro, the Shattered Blade and Mana Echoes, where every artifact entry builds a rapidly growing horde of Spirits. When you cast Trusty Boomerang, Chishiro creates a Spirit token, which in turn causes Mana Echoes to flood your pool with colorless mana based on the expanding number of Spirits you control. You then use that mana to equip Trusty Boomerang to the token, leverage its ability to bounce itself back to your hand, and repeat the process to generate infinite colorless mana and an endless army of tapped creature tokens. Meanwhile, Tannuk, Steadfast Second sits comfortably in the background, making your entire sequence possible through its haste-granting and alternative casting methods.
