Lazier Goblin

Once you motivate a creature, it remains motivated for you for as long as it remains on the battlefield. If another player gains control of it, that player must motivate it before it can attack or block, but if you regain control of it, it’s still motivated for you.

Paying a creature’s motivate cost is a special action that its controller may take any time they have priority during their main phase with no spells or abilities on the stack.
