There will be always people looking for a cheap way, and there will be always people looking for true fun.
It's impossible, said pride. It's risky, said experience. OU suspect, yelled Smogon.
Join Team Aqua, we have hot girls
I bet you didn't notice the guy behind
Reshiram/Zekrom being determined by the secret ID. Either way I am pretty certain s/he would have a Zoroark, and having all three Unova starters is perfectly logical all things considered. Plus this would enable the team to appear without the use of Memory Link. Whether you encounter Hilbert or Hilda would obviously just be determined by the gender you are playing now.
+ Black 2: 2581 1942 8822
Serperior - Magmortar - Lucario - Zororak - Espeon - Vaporeon
Plus GF could just generate the teams the same way they do the Rivals team so that its not the same every playthrough
Seems to me to be just a feature implemented into BW2 to connect it with BWMemory Link is a new feature that allows players to sync both the original Black and White with Black 2 and White 2 together via Nintendo Wi-Fi Connection or DS Wireless Communications. With this feature, the player can access new game features and interactions in Black 2 and White 2. The player may need to finish the main story in their Pokémon Black or White games to see some of the flashbacks.
I don't see why that means it couldn't be expanded and connect BW2 with Gen 6 if Unova and the new region are related in some way but it's a big if. Id like to see it have ties to Unova definately, I am curious as to the region where Hilbert and Hilda went, perhaps it's this region and if so, Id like them to appear in some way.
Honestly, I don't think memory link, or anything like that, will factor into a team for Hilbert/Hilda (if they even make an appearance (which is unlikely IMO) aaaaaand, if we even get to battle them (which is even more unlikely IMO)).
If anything, their team will be determined similar to how Red's team was in GSC/HGSS,
