The main purpose of it here is to get arcanine (ex) in
play, but it's also nice to have a growlithe with some
helpful abilities in your deck. Apart from Base
growlithe and Neo Destiny Growlithe, I'd say all
growlithe's are about even. I'd probably go with the
Growlithe from Sandstorm, because it hits your opponent
back from a so called "gust-KO" (when your opponent uses
gust of wind to swap one of your pokemon and KO it).
But as Arcanine isn't really good here, try to avoid
using growlithe's at all.
There isn't that much choice here, you either use the
Fire red, Leaf green growlithe or the Legend Maker one,
I don't like the FrLg one much even though it has 60 HP.
so LM growlithe is more than welcome here.
it's a very decent basic pokemon here, so you could use
it if you didn't have any evolution lines in your
booster packs. and if you have arcanine ex, ... yea.
