This has been causing some confusion at a local tournament lately:
If Player A summons "Zaborg the Thunder Monarch" targeting Player B's face down monster and Player B activates Enemy Controller offering his facedown monster.
Will Zaborg's effect dissappear or "retarget?" The latter, as far as I know, doesn't happen in Yugioh.
On the FAQ it says on Zaborg:
"You have to destroy 1 monster. If there are no other monsters then you have to destroy 'Zaborg the Thunder Monarch'."
But it also says
"Zaborg the Thunder Monarch's effect targets."
Usually when a target has left the field an effect dissappears, but this set of rulings is contradicting it self.
Answer:
When "Zaborg the Thunder Monarch's" effect activates, a legal target must be selected at that time.
In this case Zaborg selected a face-down Monster Card. In chain, Player B activated "Enemy Controller" and selected the second effect, Tributing that very same face-down Monster Card to pay the activation cost.
When the Chain resolves, "Zaborg the Thunder Monarch" wants to destroy its intended target, but it cannot do so because the intended target is no longer on the field. As a result, no monster is destroyed by its effect.
The first ruling you refer to is intended to remind us that we cannot decide to just "skip" Zaborg's effect because we don't want to use it. We are forced to activate the effect when Zaborg is successfully Tribute Summoned. We don't have a choice. And if Zaborg happens to the be the only monster on the field... he is forced to target himself.
