Hmm... I have a Salamence card that uses fire & water energy, but it's of the "Colorless" type... & I've seen a Salamence EX card that is a water type, & had a Poke-body (or was it a Poke-power?) that could change it's type to fire....
& speaking of which, my first deck was a Water/Electric one...
I think it was called "Turmoil theme deck"...
Also, if pokemon was real, & I've started my jouney at 10 years old, (I heard that is the typical age when people start their pokemon quests)
I would've chosen Squirtle... my allergies (of which I don't have anymore) would not permit me to have Bulbasaur, & I've would've been too intimidated by Charmander's fire...
