Rulings

(7/1/2012)
The effects of Xathrid Gorgon's ability don't depend on the petrification counter. If that counter is removed, the creature remains a colorless artifact with defender, and so on.
(6/8/2016)
Activated abilities contain a colon. They're generally written "[Cost]: [Effect]." Some keywords are activated abilities and will have colons in their reminder text.
