Question: Why is it that you can use BW/ORAS mons/moves/abilities in a Gen 4 custom game but you can't use "future" stuff for any other generation's custom game? There was a tournament a while back (Time Travel Tour) that dropped a different set of future mons into DPP OU for every round, and it was really neat. Is there any reason why Gen 4 can do that while the other gens reject you if you try?
Like, it'd be interesting to see how, say, ADV stuff could work in GSC where the metagame is just so different, you know? The underlying mechanics of many future things can be thrown back into older gens: Calm Mind, for example, could theoretically exist in GSC because the Special stat split is present there and Curse already exists. (As opposed to RBY where it might get weird with only one stat?) Snow Warning could definitely exist in ADV because Sand Stream does the exact same thing already. I'm not saying we try to implement Megas or something ridiculously unprecedented into GSC, but for stuff that has a foundation in older gens, it could be fun to mess around with.
Some replays:

This replay shows a Volcarona and Talonflame. Volcarona can use Quiver Dance and Cristal stated on the tournament thread that she had a Gale Wings Talonflame even though it didn't really accomplish much. (It scared out the QD Volc, but you wouldn't have been able to tell it was Gale Wings otherwise.)

Replay from the finals of the Time Travel Tour in which Aegislash is actually able to use Stance Change properly in a Gen 4 environment!
I was testing some stuff last night in Gen 4 Customs, and you can actually even Mega and use the Mega abilities that "shouldn't" exist. I was able to KO a Mismagius with M-Pinsir's Return, showing that Aerialate and Mega Evolution works. Fairy typing is weird in that it doesn't have any resistances or weaknesses (I tested with a Dragon Claw/Close Combat/Sludge/Iron Head Salamence and nothing was SE/resisted/immune), but Moonblast does hit Salamence for SE damage. I have no idea what that's about.
So why should anyone care?
Well, we already have the "What If?" thread which is a very fun read if you like theorymonning, and this shows that that theorymonning could easily be put into practice. Instead of a few vague posts on a certain topic, you could create basically a pseudo-OM in an old gen, complete with replays. It would be a bit of fun in metas that haven't really changed too much in years. (Excepting RBY Body Slam and ADV Sleep Talk mechanic changes, of course.) It'd also allow for the creation of more Time Travel Tour-esque/"non-standard" tournaments for older gens. RBY probably wouldn't handle a lot of this stuff, but at least GSC/ADV could have some fun.
I know that no one probably cares because it's such a miniscule, unimportant thing that no one really wants to waste time with and because SPL is coming up, but I just thought I'd throw it out there. Zarel's latest teambuilder update means Old Gen development is basically done for now, as far as I can tell, so this might be a fun thing to low-key work on?
Sorry for taking up your time.
I just want a CM Raikou in GSC.
