Artifact Creature — Golem

The effect of Guardian of the Ages’s triggered ability doesn’t wear off as the turn ends. Losing defender and gaining trample last indefinitely.

Once Guardian of the Ages has lost defender, its triggered ability will no longer trigger when a creature attacks you or a planeswalker you control (unless it has somehow gained defender again).
