First up, the Enigma Stone is availlable through Nintendo Wi-Fi from now until August 27th. this myserious item will enable HeartGold ans SoulSilver players to catch the Lati that is normally unavailable in their version (Latios in HeartGold, Latias in SoulSilver). Take it to the fossil-reviving guy in Pewter City Museum, and he will turn it into the Soul Dew. Steven Stone will then arrive and tell you about the Soul Dew's connection to Latios and Latias. Leave the Museum and Latias or Latios will be waiting for you. He/she will be at Level 40.
In the TCG front, the HeartGold/SoulSilver: Undaunted set Prereleases will occur on the weekends of August 7-8, 14-15, and 21-22. This set features some of the best Pokemon Prime and Pokemon Legends yet, as well as cool new Eeveelutions, Supporters, and Stadium cards. As always, check www.pokemon.com for times and locations!
Also, Worlds is coming up in mid-August. The top players from around the world will gather in Hawaii to show the world what they've got! Best of luck to all participants!
After Worlds, the Modified TCG format will shift to Majestic Dawn-on. This means no more Claydol (sniff)! Adjust your decks accordingly, Trainers!
