Just a quick combo here.  In the Gym II (aka Gym Challenge) set, there
is a card called Giovanni (spoiler, as always, courtesy of Edo):

Giovanni
Type:  Trainer
Effect:  Choose 1 of your Giovanni Pokemon.  If that Pokemon
  was played this turn, you may evolve it.  Or, if that Pokemon
  was Evolved this turn, you may Evolve it again.
  (If you choose to Evolve the Pokemon, put the Evolution card
  from your hand on top of that Pokemon.)
Picture:  Giovanni
No card number (Rare Hologram)

We all have seen the new Promo Eevee, have we not?  Just in case, here
are the stats (I'm typing this up myself from a scan on Ebay)

Eevee
30HP
W:F
R:P
Retreat:  0
Power:  Chain Reaction
This power can only be used when a pokemon evolves.  Search your deck
for a card that evolves from Eevee and attach it to Eevee.  This counts
as evolving Eevee.  Shuffle your deck afterward.  This power can't be
used if Eevee is asleep, paralyzed or confused.
C:  Bite  20
Promo Holo

This isn't exactly powerful, but it's interesting.  On your first turn,
have a Giovanni Basic and Promo Eevee in your play area.  Play Giovanni,
then evolve the Basic.  You can then use Chain Reaction!  Best used with
Dark Jolteon, and, I guess, Giovanni's Persian.  As I said, it's not
very powerful, but it's an interesting quirk of the game, and may be
useful for all you Eevee fans out there.

PS.  Scott or Pojosama, would you please put a search box on the Pojo
site, that lets you search all the articles?  It would make finding
articles so much easier, and would make following submission rule #3
(new material) much easier to follow (and thus more likely to be
followed).  I know that you can get the source for it at
www.searchtraffic.com, but there should be other sites devoted to that
service.
