Kykar, Wind's Fury + Trusty Boomerang + Mana Echoes + Rising of the Day

Kykar, Wind's Fury

Trusty Boomerang

Mana Echoes

Rising of the Day

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 loop turns a simple bounce effect into a roaring storm of mana and spirits by exploiting the synergies of your board. With Rising of the Day ensuring your tokens are instantly ready to tap, you cast Trusty Boomerang to trigger Kykar, Wind's Fury, which dutifully births a Spirit token. That new arrival immediately supercharges Mana Echoes, producing a cascading flood of colorless mana as your Spirit count climbs. You then use Trusty Boomerang's activated ability—helped along by its equip cost—to bounce the Equipment back to your hand by tapping the very Spirit it's attached to, allowing you to replay the spell endlessly and scale your resources to infinity.
