This Rayquaza was distributed to SG players with Pokemon XYORAS.
Only English wonder card, via US and JP units.

Due to the " ' " in the Original Trainer name, this Rayquaza was unable to be traded or battled with online (in Generation 6).
(It's apparently an oversight made by the in-charge of this event.)

When traded in Gen 7, the OT's name will change, and can be read about here.

On the official page for Birthday promotions, the 2nd Birthday distribution was supposed to end right before Let's Go Pikachu & Eevee launches,
and the birthday giveaway would then only be the Chansey Gift for those games.

However, either due to an oversight or perhaps a secret distribution only for those who ask for the 3DS versions of the birthday gift,
this 3rd distribution was given away only at select Pokémon Centers, provided the staff doesn't claim that such a distribution doesn't exist.
It's also possible before mid-November ended (the transition to Let's Go), staff gave away this event instead of the 2nd distribution.

In any case, some people managed to get this rare card. It was still required for players to be in their birthday month to receive this.
Identification would have to be presented upon redemption, and travelers can do so by showing their passport.
