If for example: I ring my oppenent's Airnight Parashath, can they chain Enemy Controller, tribute their Airnight, take control of one of my monsters, and thereby make the damage from Ring of Destruction non-existant?

Ring of Destruction would destroy Airknight Parshath.

Player A: Rings Airknight Parshath

Player B: Chains Enemy Controller to Airknight Parshath

Ring of Destruction is set targeted towards Airknight already so in this case it would be destroyed.

It uses the same ruling as Creature Swap does.

From: netrep
[Re: Creature Swap] Both players must have at least 1 eligible monster on the field for "Creature Swap" to be activated. If the opponent chains a card (such as "Ring of Destruction") to destroy the only monster on one side of the field, the effect of "Creature Swap" disappears.

Huh?

You realize that the cost of actually playing the second effect of Enemy Controller is to tribute the monster . . . so how exactly would it still be destroyed?

Toon whirled: Your chain is correct. Since Airknight Parshath is no longer face up on the field when Ring of Destruction resolves, Ring of Destruction will not deal damage to either player.

I though he was talking about this effect "Select 1 face-up monster on your opponent's side of the field. Take control of the selected card until the End Phase of the turn this card is activated."
I though he was saying he is going to take control of Airknight Parshath.
Sorry about that.

BTW
Thanks for the 2 corrections. I am going to stop posting in this forum unless I am 100% sure. I should have never started to post in this forum in the first place. So for no on I will stop posting unless I am 100% sure!

No worries, this is one of the best places to learn the rules.

As long as you are willing to learn and can put up with the CONSTANT corrections being made to the thousands of rulings we have then you will go far.

^_^ V

you make that sound like a bad thing....

you'll either go far, or go insane, or start flipping tables...

I started off insane SO I say Bring it!

It’s always best to remember things offered as costs are automatically taken care of at the activation of the effect. (Pg 36 of the Rule book for more info on costs)

In this case you activate the 2nd effect of enemy controller, this requires a cost tribute of one monster, and you MUST pay this at activation (Prior if you want to be technical)

So you Tribute off Airknight.

Also important to know that Chains resolve backwards. So the last thing activated in the chain will resolve first. Since Enemy Controller was the last thing activated it will resolve first. Ring will resolve last since it was activated first, but since its target is gone, it will not be able to destroy a monster or do any damage.
