The 3 combo pieces

What must be in place

An opponent controls three nontoken creatures that they own and that are not commanders.

How to execute it

  1. Deal combat damage to an opponent using Etrata, triggering its ability.
  2. Holding priority, activate Strionic Resonator by paying {2} and tapping it, copying Etrata's trigger.
  3. Holding priority, cast Return the Favor by paying {1}{R}{R}, choosing its first mode, copying Etrata's trigger.
  4. Resolve all Etrata triggers, exiling three creatures an opponent controls and putting hit counters on them, and then causing that opponent to lose the game.
