Whenever you activate Herald of Anafenza's outlast ability, put a 1/1 white Warrior creature token onto the battlefield.

Khans of Tarkir Promos

Several creatures with outlast also grant an ability to creatures you control with +1/+1 counters on them, including themselves. These counters could come from an outlast ability, but any +1/+1 counter on the creature will count.

The Warrior token is created before the +1/+1 counter is put on Herald of Anafenza.

The cost to activate a creature’s outlast ability includes the tap symbol ({T}). A creature’s outlast ability can’t be activated unless that creature has been under your control continuously since the beginning of your turn.
