Everything said by Serebii about Electivire/Magmortar
I decided to put everything that was said about our mysterious Pokemon and Trainer Passes here so anyone entering this topic will see all of it in the first post (or at least I hope too...)
Now, we know the Pokemon are related to the Trainer Passes and that see know that remakes of Gold and Silver are NOT related to this.
"They're obtainable within game without the need for going to an event, however the means to get them is obscure and you wont know it"
"The way to get it isnt something you can do in the game..."
"If it was available in-game just by beating something, do you not think that I would have revealed it?"
"Ok let me rephrase
They're obtainable in game but through any in game methods
That make sense?"
"Come on people, if it was a method you could think of and that was do-able, it wouldn't be a secret and would be revealed by now"
"There is no way through game playing, transferring, battling etc to get them
Only a special way which will be revealed by Nintendo at a later date"
"It has nothing to do with settings either. Jesus Christ"
So, this is everything he's said. Pretty much all of that was found here:
