You control enchanted creature. Enchanted

When Bottle Trap enters the battlefield, put 4
glass durability counters on it. At the beginning
of your upkeep, remove a glass durability
counter from Bottle Trap. When Bottle Trap
has no glass durability counter on it, Sacrifice it.
(When in a graveyard, Bottle Trap isn't keeping the creature under your control anymore.)
