I've captured Lugia (already cloned several times in SS with extra Nuggets since cloning has to be done overtop of existing Pokémon), and it's going to one day be imported into Black as well - and Ho-oh when I can handle Lv.70 unless I get HG (in which case I export my team to there and zip through the game). As Victory Road is the next thing on my plate, I have to get through Route 26 and then tackle that so I can even visit the E4. Once I beat the E4, I return to Johto and catch more garbage Pokémon to clone some of my catches for transfer, or even just transfer new catches. I can then start transferring. :)
I have to study the teams of the E4 like I usually do and figure out my strategy before I go in. I know Lv.45 (Lugia) is my highest level, so I foresee some training in Victory Road in my future before I challenge.
