●The ATK boost of “Overdoom Line” starts a Chain, but does not target.
●The text on “Overdoom Line” that destroys itself is not an effect, so “Royal Decree” etc. won't stop it from being destroyed.
●Plants that were Special Summoned before the activation of “Overdoom Line” don't receive an ATK boost when “Overdoom Line” is activated.
●Monsters that get an ATK boost from “Overdoom Line” keep the boost even if they become a Type other than Plant-Type.
●If a monster receives the ATK boost from “Overdoom Line” but is flipped face-down, it loses the boost, even if flipped face-up again while “Overdoom Line” is still on the field.
●You can't activate “Overdoom Line” during the Damage Step.
●While “Imperial Custom” is active, “Overdoom Line” can't destroy itself, so it will remain on the field. Its effect will also remain.
