Riders of the Mark

This spell costs {1} less to cast for each Human you control.
Trample, haste
At the beginning of your end step, if Riders of the Mark attacked this turn, return it to its owner's hand. If you do, create a number of 1/1 white Human Soldier creature tokens equal to its toughness.

The Lord of the Rings: Tales of Middle-earth

If Riders of the Mark leaves the battlefield before its triggered ability resolves, you can't return it to its owner's hand from its new zone.

Use Riders of the Mark's toughness as it last existed on the battlefield to determine how many 1/1 white Human Soldier creature tokens to create.

You won't create tokens if Riders of the Mark is returned to your hand by an effect other than its own  triggered ability.
