Night Market Lookout
Creature — Human Rogue
Whenever this creature becomes tapped, each opponent loses 1 life and you gain 1 life.
The Consulate rarely cracks the coded announcement of a night market's location before dawn, and enforcers are taken care of if they wander too close.

This is a triggered ability, not an activated ability. It doesn't allow you to tap Night Market Lookout whenever you want; rather, you need some other way of tapping it, such as by attacking.

For the ability to trigger, Night Market Lookout has to actually change from untapped to tapped. If an effect attempts to tap it, but it was already tapped at the time, this ability won't trigger.
