Kykar, Wind's Fury + Trusty Boomerang + Mana Echoes + Samut, Voice of Dissent

Kykar, Wind's Fury

Trusty Boomerang

Mana Echoes

Samut, Voice of Dissent

How it works

1. Cast Trusty Boomerang by paying 1.
2. Kykar triggers, creating a 1/1 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 token by paying 1 and tapping it, tapping a creature a returning Trusty Boomerang from the battlefield to your hand.
6. Repeat.

This clever loop turns the endless casting and returning of Trusty Boomerang into a self-sustaining engine. Every time you cast it, Kykar, Wind's Fury rewards you with a Spirit token, which in turn triggers Mana Echoes to generate a growing surge of colorless mana as your horde of Spirits expands. Meanwhile, Samut, Voice of Dissent ensures your newly minted tokens have haste, and you can even use her untap ability if needed, though here the equipment itself does the heavy lifting: by paying to equip and activate Trusty Boomerang right off the Spirit, you bounce the artifact back to your hand to recast it all over again.
