Hello.  I wonder if you could clear this up.
My deck runs a Fossil Horsea, a Misty's Horsea, and a Misty's Seadra.  Would
it be possible to evolve a Fossil Horsea into a Misty's Seadra, a Misty's
Horsea into a Fossil Seadra, or any other combanation like that?  I'm
wondering because my Misty's Seadra says "Evolves from Misty's Horsea", not
just from any Horsea.

Thanks, Allen

You have to treat Gym Pokemon completely different from their non-gym counterparts.  Horsea and Misty's Horsea have absolutely nothing in common except the word "Horsea" and of course they both are water Pokemon.  So, you can not intermingle the sets for evolution purposes.
