I'm surprised I actually won this. No one bid against me, amazingly. o_O
I bought the Espeon/Charizard set about 6 years ago, but have since sold/lost the Charizard, and whereas I DO have Espeon still, my Espeon is dirty and worn (I carried it in my pocket at work for good luck for many years.)
It is amazing I was able to find it again - (thank you, juumou!)
I can't remember exactly what else is in the set - no other eeveelutions, for sure, but I believe there is a Hondoom/Houndour, first version of Suicune (different than the Ruby/Sapphire V-trainers), Cyndaquil, Raichu, and a few others.
