The Pokebeach has all the scans of the Japanese HeartGold/SoulSilver TCG set out, and I must say, my initial impression has been favorable. I highly enjoy the art (the evolution items in the card art of the Pokemon that need items to evolve is a very nice touch), especially on the new "Great" and "Legend" Pokemon. Several old Trainer cards have been reprinted (Full Heal, Moo-Moo Milk, Fisherman, a Supporter-ized Bill, and especially Prof. Elm's Training Method and Copycat), and Double Colorless Energy returns after a decade-long absence. I'll post more on the latter's return later.

Hope to see this set come February!
