Willbreaker

Oracle Text
Whenever a creature an opponent controls becomes the target of a spell or ability you control, gain control of that creature for as long as you control Willbreaker.
Card Rulings
6/22/2015 If Willbreaker leaves the battlefield, you no longer control it, and its control-change effect ends.
6/22/2015 If you lose control of Willbreaker before its ability resolves, you won’t gain control of the creature at all.
6/22/2015 If another player gains control of Willbreaker, its control-change effect ends. Regaining control of Willbreaker won’t cause you to regain control of the creature.
As I understand it, the fight/bounce/effect of the targeting spell or ability will fizzle as an invalid target. Willbreaker's controller will get the creature without further effects.
In the case of controlling multiple willbreaker's the controller must identify the order of their triggers and mark which Willbreaker controls what creatures.
Any corrections to the above???
