Continuous Monster Effects typically come into play as soon as the monster is successfully Summoned, and don't disappear until the monster is removed from the field or flipped face-down.
"Jinzo" and "Spell Canceller" are two such cards with Continuous Effects. Continuous Monster Effects do not start a Chain, therefore they cannot be negated by "Divine Wrath", "Pulling the Rug", "Doomcaliber Knight" or "Shadow-Imprisoning Mirror". However, they can be negated by other continuous effects that negate Effect Monsters' effects (such as "Skill Drain").
