I'm restarting my Diamond version over and over again and trading the Entei to my Soulsilver
Right now I have 8 Entei's, man I'm gonna be updating my sig a lot.
Haha, good thinking. I actually started doing that a couple of days ago. I have a spare Diamond version and I decided to just restart it over and over again in order to keep getting more Shiny Entei from the Wi-Fi event. I plan on doing the same thing on my spare HeartGold version once the Shiny Suicune Wi-Fi event starts. I find that it's easier to obtain the Wi-Fi event Pokemon in HG/SS since it's faster to get Mystery Gift activated in those games.
