Ok, I was asked this question in a PM. Just want to make sure that I made the correct ruling.
Player A has two face up Gemini Elf and a set Aqua Chorus.
Player B has an empty field.
Player A attacks with one of the two Gemini Elf. Player A activates Aqua Chorus in the Damage Step.
Now stop.
The question was, "Can I activate Aqua Chorus in the Damage Step?" and now look at Aqua Chorus's card text.
"If there are monsters with the same name on the field, increase the ATK and DEF of all of those monsters with the same name by 500 points."
Bolded text is what I was looking at when I determined my ruling. The following is my ruling.
"Aqua Chorus can activate in the Damage Step "only" if there's monsters of the same name on the field. If not then Aqua Chorus can't be activated in the Damage Step."
I was basing this ruling not only off the above bolded card text of Aqua Chorus, but from the results about the Deck Devastation Virus v.s. My Body as a Shield.
We came to agreement that Deck Devastation Virus couldn't get negated by My Body as a Shield if there wasn't a face up monster with low enough attack points for My Body as a Shield to register. It has to see that a monster is definately being destroyed; otherwise, you're going off face down monsters which are considered to have no stat values until flipped face up.
To me this is a similar case with Aqua Chorus. Aqua Chorus would have to require at least two monsters of the same name on the field to recieve the attack boost.
Now lets use the same example with Gemini Elf situation.
Player A has one Gemini Elf and a set Aqua Chorus.
Player B has a completely empty field.
Player A attacks with Gemini Elf. Player A activates face down Aqua Chorus in the Damage Step.
Now stop.
Is this legal? Aqua Chorus isn't giving any attack boost to anything; thus, it's activation would be illegal.
So is my ruling, "Aqua Chorus can activate in the Damage Step "only" if there's monsters of the same name on the field. If not then Aqua Chorus can't be activated in the Damage Step." accurate and correct?
