The Pokémon Company is holding two distribution events in October, one is for Zeraora and the other is for both Gen 5 box Legendaries, Zekrom and Reshiram.

Zekrom and Reshiram will be distributed through Target from Oct. 19-28. Like other Target and Gamestop distribution events, players simply have to go to the retailer and ask for a card that contains a serial code. No purchase is necessary.
