General's Enforcer

Legendary Humans you control have indestructible.
{2}{W}{B}: Exile target card from a graveyard. If it was a creature card, create a 1/1 white Human Soldier creature token.

Fallout

Ikoria: Lair of Behemoths

Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to a legendary Human you control may become lethal if General's Enforcer leaves the battlefield during that turn.

Only creatures are Humans. Planeswalkers such as Lukka and Narset who represent human characters aren't affected by General's Enforcer.
