Darkmoon cards are in 4 decks of 8 cards,
Portals deck,
Beasts deck,
Elementals deck,
Warlords deck,
They drop as "Ace of Portals", "Two of Portals", "Three of Portals" etc. By the looks of it they're only dropping off high lvl elites, i'm not sure if they're dropping off high lvl non elites.. If u find out plz post.

So far they have dropped from mobs in these places:
Stratholme, Blackrock Depths, Blackrock Spire, Burning Steppes, Scholomance, Western Plaguelands, Felwood, Silithus, Eastern Plaguelands, Feralas, Dire Maul, Searing Gorge, Molten Core...
Once you have a complete deck of cards you can hand them in to receive one of these 4 epic trinkets. - Note that i don't know which deck gives which reward and I'm guessing those are not fake pics.
Also, if you collect 1200 tickets (I dunno any more info about these atm), you can receive an epic necklace like these two here.
If anyone finds out anymore useful info plz post.
