Fallowsage
Creature — Merfolk Wizard
Whenever this creature becomes tapped, you may draw a card.
Memories of ages past are said to swim the minds of lounging fallowsages.

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

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