Holon Research Tower
EX Delta Species
This card stays in play when you play it.
Discard this card if another Stadium card comes
into play. If another card with the same name
is in play, you can’t play this card.
Each player’s basic Energy cards attached to
Pokémon that has δ on its card are both their
usual Energy type and (M) type but provide only
1 Energy at a time. (Has no effect other than
Stadium cards are an interesting Trainer: the only
type to stay in play until forced out by another
card effect (well, some Pokémon Tools last
until another effect discards them or the Pokémon
they are attached to is KO’d).
Stadium’s have a “global effect”, that is, they
affect both players equally (occasionally a slight
preference to the controller, but that usually
involves terms of resolving overlapping effects).
So you generally like it when a Stadium has a pretty
specific effect. In this case, Holon
Research Tower is useless unless you use Pokémon
δ, and even then, if you already have your Metal
Energy requirements met, this card isn’t too
useful. For dedicated Pokémon δ decks, it’s pretty
nice. Most promising Pokémon δ I have seen need a
Metal Energy for an attack cost, and this allows any
basic Energy to provide Metal or its normal type.
Keep in mind, if you have a Holon Energy and
a Basic Energy type it references, you won’t lose
that effect: the wording is just means that if you
had a Lightning Energy on a Dragonite
δ, you could treat it as a Metal Energy or treat it
as a Lightning Energy when checking to see if
you met attack requirements, but not both at the
exact same time.
Perhaps one of the best default Stadiums for Pokémon
δ decks. There’s not much to combo with it due to
its basic nature: if you need to fill a Metal Energy
requirement, it’s an easy way to fill it. Just
remember that it only affects Basic Energy cards,
and that you’re not getting the damage reduction
effect of the actual card, Metal Energy. So
if you need to get Metal for that reason, use more
search cards, not this.
One could risk using this with EX Hidden Legends
Metagross, as then one could move Basic Energy
around as well, but it seems to delicate a combo,
especially since any basic Energy on Metagross
would be unaffected.
1.5/5-Not a lot of Basic Energy played here outside
of select decks (e.g. Raindance). Besides, most of
the Pokémon δ aren’t well suited to this format.
3.75/5-Note that this score reflects its use in
Pokémon δ centered decks that could use a little
help “making” Metal Energy.
4/5-So many of the new Pokémon have a Metal
requirement for at least one attack, this may
actually be more important than draw power for those
A nice way of supporting these new Pokémon δ. It’s
no Rocket’s Hideout, but it does seem on par
with Rocket’s Tricky Gym or Team Magma’s
