702.168 Clockwork

702.168a Clockwork represents a static ability and a triggered ability. "Clockwork N" on a creature means "This creature enters with N +1/+1 counters on it" and "Whenever this creature becomes tapped, remove a +1/+1 counter from it at the beginning of the next cleanup step." "Clockwork N" on a noncreature permanent means "This permanent enters with N charge counters on it" and "Whenever this permanent becomes tapped, remove a charge counter from it at the beginning of the next cleanup step."

702.168b Clockwork without a number on a creature means "Whenever this creature becomes tapped, remove a +1/+1 counter from it at the beginning of the next cleanup step." Clockwork without a number on a noncreature permanent means "Whenever this permanent becomes tapped, remove a charge counter from it at the beginning of the next cleanup step."

702.168c Some spells and abilities refer to a "card with clockwork" and "its counters." If that card is a creature card with clockwork N, "its counters" means N +1/+1 counters. If that card is a noncreature card with clockwork N, "its counters" means N charge counters.

In card text or details pages, write the mechanic's code name (playtest name) between square brackets, like "[Crittercast]", "[Bushido 1]" or "[Delay 4 {2}{R}{R}]". It will be expanded to the mechanic's name plus reminder text, such as "Suspend 4 – {2} {r} {r} . (Rather than cast this spell from your hand,...)"
To expand a mechanic's name but not its reminder text, include parentheses at the end of the square brackets: "[Crittercast()]", "[Delay 9 {R}()]".
