Nintendo is clearly staffed by brilliant people who thought it was a good idea to release the most anticipated app for the biggest games on the 3DS around Christmas, where a lot of people would be receiving new consoles and handhelds.
On the topic of Petal Blizzard Meganium, I'm not inclined to use it over other physical, bulky Grass types. There is absolutely no way it can compete with Virizion, hands down. Torterra suffers from a speed disadvantage, but STAB EQ and Stone Edge make it scarier to switch into. I personally would rather give that teamslot to BU Gogoat. It suffers from 4mss, but it has staying power that Meganium does not.
