Feldon of the Third Path + Worldgorger Dragon + Strionic Resonator + Garna, the Bloodflame

Feldon of the Third Path

Worldgorger Dragon

Strionic Resonator

Garna, the Bloodflame

How it works

1. Activate any number of permanents by tapping them, adding at least 4.
2. Activate Feldon by paying 2 and tapping it, targeting Worldgorger Dragon.
3. Holding priority, activate Strionic Resonator by paying 2 and tapping it, copying Feldon's ability targeting Worldgorger Dragon.
4. Resolve the copy of Feldon's ability, creating a token copy of Worldgorger Dragon.
5. When the Worldgorger Dragon token enters, its first ability triggers, exiling all other permanents you control.
6. Resolve the Feldon ability from step 2, creating a token copy of Worldgorger Dragon.
7. When the Worldgorger Dragon token enters, its first ability triggers, exiling all other permanents you control.
8. When the Worldgorger Dragon token created in step 4 leaves the battlefield, its second ability triggers, returning all cards exiled with it to the battlefield.
9. Repeat.

This brilliant loop relies on Worldgorger Dragon's entrance trigger to perpetually exile and return your entire board, fueled by the repeatable mechanical engine of Feldon of the Third Path. By using Strionic Resonator to duplicate Feldon's creation ability, you stack multiple dragon triggers to infinitely cycle your permanents in and out of exile. Because Garna, the Bloodflame gives your creatures haste and effortlessly recycles your graveyard, every iteration refreshes your board state while generating staggering amounts of mana and triggers.
