At the beginning of each end step, if this creature dealt damage to an opponent this turn, put a +1/+1 counter on it.

Amid this whirling hurricane of blades, there is no calm eye in which the hapless can find shelter.

If Dunerider Outlaw dealt damage to an opponent who later left the game before that turn's end step, its ability still gives it a +1/+1 counter.

Whirling Dervish's triggered ability checks to see if it dealt damage during the turn to an opponent of its current controller. If it dealt damage to player A, then player A takes control of it, the ability doesn't trigger.

Whirling Dervish's triggered ability gives it at most one +1/+1 counter each turn, regardless of how many opponents were dealt damage beyond the first.
