Anyone know what's up with this event?
They said every Keg, I've opened for kegs today 1 earlier when the event was posted and 3 more a few minutes ago.
The 1st keg gave me a rare but those last 3 didn't....
Am I missing something?
A rare card doesn't have to be a golden or a silver card, bronze cards can also be rare. Rarity of a card is depicted by a small square in the bottom-right corner of a card. For instance Slyzard, which is a bronze card, is also rare (Slyzard dropped for you from a keg recently).
rares are bronzes, and in addition to the little blue gem, in the keg screen their description has a big blue line next to it (and the card has a blue glow when moused over), the other colors are as noted by @Clxmj
