Dragonback Assault + Bladewing's Thrall + Ashaya, Soul of the Wild + Yahenni, Undying Partisan

Dragonback Assault

Bladewing's Thrall

Ashaya, Soul of the Wild

Yahenni, Undying Partisan

How it works

1. Cast Bladewing's Thrall by paying 2.
2. When Bladewing's Thrall enters, Dragonback Assault triggers, as Bladewing's Thrall is a land due to Ashaya.
3. Holding priority, activate Yahenni by sacrificing Bladewing's Thrall.
4. Resolve the Dragonback Assault trigger, creating a 4/4 Dragon creature token.
5. When the Dragon enters, Bladewing's Thrall triggers, returning itself from your graveyard to the battlefield.
6. Repeat from step 2.

This intricate engine transforms simple creature movement into an unstoppable loop by turning your squad into dual-threat powerhouses. Ashaya, Soul of the Wild does the heavy lifting here, turning Bladewing's Thrall into a land so that its own entrance triggers Dragonback Assault's damage and its subsequent landfall ability. By sacrificing the Thrall to Yahenni, Undying Partisan in response, you clear the way for Dragonback Assault to spawn a Dragon token; that very same token then fulfills the condition to bring Bladewing's Thrall right back from the graveyard.
