You wouldn't tease your pals, would you?
Would I really take the time to:
start the game
select an old Legacy deck
wait approximately 1 hour to find a match
play the match
save the log
painstakingly alter the log / replace all instances of one Pokemon with another
Just to get a rather vague and dubious point across ?
Of course I would (sorry Sakura)
Without a shred of doubt, I can say that this log is legit.
So, what's the point ?
One the one hand I wanted to showcase how easily one can forge a log, or at least parts of it. Trying this over the course of an entire game would probably be a bit trickier, as you had to keep damage consistent and include attacks and everything, but it's manageable never the less.
Before the log both of you argued that the OP simply made an error. How could anyone get away with playing a GX Pokemon in Legacy, or with Ghetsis in Expanded?
Naturally that was also my obvious conclusion. Especially given that a lot of players probably own decks that can be run in Legacy and in Expanded it easy to see how someone could make a simple error and not realize that he's currently playing the wrong format.
Additionally, unique bugs in this game are pretty much non-existent and in small cases where individual solutions apply, it usually a hardware, rather than a software problem.
If you can't replicate the bug under the same circumstances, chances are that either a critical info is missing, or that someone made an error.
That being said, just because you can't replicate a bug on the first try doesn't necessarily mean that the OP is lying. Heck, if I stuck to my story I'm sure that I could convince both of you that I encountered a legit bug, despite your inability to reproduce it.
Rather than argue about the credibility of the OP (which honestly won't go anywhere), we should either look out for a different solution (I think we can all agree that you are unable to enter a mode with a deck that isn't legal in the format).
One thought that came to my mind yesterday when I was waiting for a match (it probably took a couple of minutes and I was playing at a reasonable time for both Europe and the US).
Imagine you have a deck that is legal in Expanded and in Legacy and I have a deck that is legal in both formats, except I run 1 copy of Ghetsis. You queue for Expanded and I queue for Legacy.
The developers already confirmed that the algorithm will eventually increase the range of potential opponents if it takes too long to find a match (I know you don't believe in the ELO, Rob, but we can both agree that there is a match making happening in the background).
Now, what if that algorithm identifies both of our decks as being legal to be paired against (if it wouldn't be for Ghetsis we'd probably both think we just had a match in our respective formats)?
While the chance of that happening is extremely low, with all the weird bugs that PTCGO has produced over the years it certainly wouldn't be the strangest and yet something that is almost impossible to re-create.
It's a long shot and the obvious answer is probably the right one (in fact I'm 99,9% on your side),
but to reach that conclusion we probably didn't need 30 posts :S.
Happy holidays guys <3
The shadows of the abyss are like the petals of a monstrous flower that shall blossom within the skull and expand the mind beyond what any man can bear, but whether it decays under the earth or above on green fields, or out to sea or in the very air, all shall come to revelation, and to revel, in the knowledge of the strangling fruit - and the hand of the sinner shall rejoice, for there is no sin in shadow or in light that the seeds of the dead cannot forgive...
