Rulings

(8/15/2010)
Primal Cocoon's first triggered ability triggers at the beginning of the upkeep of Primal Cocoon's controller (who is not necessarily the enchanted creature's controller).
(8/15/2010)
The counters are put on the creature, not on Primal Cocoon. They'll stay on the creature even after Primal Cocoon is sacrificed or otherwise stops enchanting that creature.
