Does returning a token unit to hand trigger its Deathknell?

Question

Accepted Answer

No, returning a token unit to your hand does not trigger its **Deathknell** ability.

According to **Rule 808.1.d**, the trigger condition for **Deathknell** specifically requires the permanent to be **Killed** and sent to the **Trash**.

Additionally, RiftJudge FAQ #10284 clarifies this interaction:
> "Q: Does Death Knell still proc if the unit is sent back to hand?
> A: No, *Deathknell* does not trigger if a unit is returned to your hand.

> According to **Rule 808.1.d**: 'The Trigger for this effect is the Permanent being Killed and sent to the Trash.' Because *Deathknell* requires the unit to be killed and move to the trash, if a card effect causes that unit to be returned to your hand, the 'death' event never occurs. Consequently, the *Deathknell* ability is never triggered."

While tokens are game objects that can possess **Deathknell** (as established in FAQ #9398), the requirement to be killed and move to the trash remains unchanged for them. Moving a token to your hand (or any zone other than the trash) prevents the "death" event from occurring, so the ability cannot trigger.
