Etrata, the Silencer + The Peregrine Dynamo + Abstruse Archaic

Etrata, the Silencer

The Peregrine Dynamo

Abstruse Archaic

How it works

1. Deal combat damage to an opponent using Etrata, triggering its ability.
2. Holding priority, activate The Peregrine Dynamo by paying 1 and tapping it, targeting Etrata's trigger.
3. Holding priority, activate Abstruse Archaic by paying 1 and tapping it, copying The Peregrine Dynamo's trigger, targeting Etrata's trigger.
4. Resolve both Peregrine Dynamo triggers, copying Etrata's trigger twice.
5. 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.

This lethal loop weaponizes Etrata, the Silencer's unblockable combat trigger by turning a single successful strike into a game-ending flurry. When Etrata connects with an opponent, her delayed-loss trigger goes on the stack, and you immediately tap The Peregrine Dynamo to copy it. By using Abstruse Archaic to copy that very activation, you end up with multiple stacked copies of the legendary assassin's ability. Resolving them all exiles three creatures under your opponent's control with hit counters and instantly fulfills the three-card loss condition, bypassing the need to wait three separate turns while keeping Etrata safely shuffling back into your library.
