Zekrom (white), Reshiram (black), Landorus, Tornadus (black), Thundurus (white), Cobalion, Virizion, Terrakion, Keldeo, Meloetta, Genesect and Kyurem.
Like Keldeo and Meloetta, you get Genesect in an event.
no one will ever trade keldeo, genesect or meloetta to you cos it is a event that hasn't happen in japan, except if you ask someone with a glitch.There are alot of People out there utilizing Action Replay to obtain Keldeo, Genesect and Meloetta. If you don't mind a cheated 'mon they are out there. I, in fact, have them as well as their shiny counterparts. (US)
There will be Keldeo, Meloetta and Genesect cards in the future. America hasn't had the event where you get them in the game, so it will be a long time.
The event is not out yet so wait pls .
Keldeo, Meloetta and Genesect are all event exclusive pokemon. However, their respective events have yet to be released (Outside of Japan at least) and so they are currently unavailable.
You can't, even in Japan. You can only get it through cheats. If anyone offers you a Meloetta, Genesect, or Keldeo, it is not genuine. It is fake. YOu can only get them through events.
