Because damage remains marked on a creature until the damage is removed as the turn ends, nonlethal damage dealt to a creature may become lethal if Oko's second ability changes its toughness during that turn.

If either of the target permanents is an illegal target when Oko's last ability resolves, the exchange won't happen.

Oko's second ability may target a permanent that is only temporarily an artifact or a creature, such as Oko, the Trickster. If this happens, the effect causes that permanent to remain a green Elk creature even after the temporary effect expires.

If the affected creature gains an ability after Oko's second ability resolves, it will keep that ability.
