As of yesterday, Japanese Wii owners can download the "Meteor of Crimson" battle card for Shooting Star Rockman 3, a giga class card formerly available to Wave Master tournament participants .
When used, MoC attacks the entire battlefield twice with a whopping 300 x 2 attack power. 600 damage in total. Wowza.
MoC is available for a limited via "Everyone's Nintendo Channel", expires on July 28th, 2009. Hopefully, we'll see a similar method of obtaining the card on our shores.
