The original announcement said that top 64 players of the North American Championship at gencon and the Euros got this card. Were they actually handed out?

Yep, and they look even better in person.

?

Did all top 64 players get them, like the article said, i.e. everyone at both events?

for Euros, yes.

Well if anyone has a spare, I have a gloss double sided flotilla card to trade

Yup, they're very pretty cards. And they did manage to track down enough for everyone at Euros.

I'd also like to trade for such a card if anyone would part with their copy ?
