I don't really get what you said so I'll just explain it period.
You should use PMGE 1.4.2 and load the Raikou, Entei, Suicune, and Celebi Wondercard and Gift files from the Event Contribution thread in the Events Section.
Export an AR code for whatever game you're using. Activate the code in that game and receive the Entei, Raikou, Suicune, and Celebi.
Unlock the Pokerelocator in your Black/ White game. Then just follow the instructions it gives you to transfer the Events.
