Flygon Winner

[Azure]

I recently got four copies of Flygon from the Dragon series.
Two of them are holo while they should have been non holo and two of them are holo with a Winner stamp on them. What are they?

Promos given away at the Pokemon League. There was a whole set of cards with the Winner stamp.

By the way, here is a scan of them. So it wasn't for any special event right?

Promos given out at League tourneys. And can't forget the jumbo versions of each....
