You have to use the Unova Link, and you can use the Infrared connection with someone who has Pokemon Black 2 (which has Black City), and receive the key from them.
Same as in the games Black and White: Unova.
it is unova dex #000.
I think the Isshu region is the same as Unova. And, no you can not trade pokemon from Unova/isshu to any other region because the older games have no data on the new pokemon.
dude unova is the region not a city
the legendary trio of unova are Cobalion, Terrakion, and Virizion
You're already in the Unova region in Pokémon Black. The region that Pokémon Black takes place in is the Unova region.
No because , the unova region has different qualities and settings. so you can only catch unova pokemon. but there is a cheat to get celabi to unova.
The Iceberg Key is an exclusive to White 2, if you wish to get it in Black 2 then you need to do the Unova Link function
Including Genesect:-155 Pokemon in the Unova region.
You cannot find a wild Snivy in the Unova region.
In the Unova arc of the anime, Ash's egg hatches into a Scraggy.
