To be fair, it's still somewhat trading among the elite/cloners, admittedly with some people like yourself managing to break in, though. Obviously, as the cloning continues, standards will drop, but I wouldn't go putting in a lot of hope for seeing a Genesect just yet.
But you don't need event 'mon to complete the dex anyways, and I'm guessing/hoping that when the rest of the world gets Pokebank, standards will really drop.
My only tip would be to deposit stuff into the GL system, rather than trying to search/seek out stuff, as most reasonable trades get snapped up instantly atm. Honestly, I'm having fun just breeding semi-rare stuff from Friend Safaris in between Le Wow evolve Runs, and getting trades for stuff I'm missing.
On a sidenote, I need Sigmaah to teach me his timing precision. Mine sucks.
