Articuno! One of the big birds from the first generation. For a legendary bird, it falls a bit short in today’s field. For PvE, you just don’t see much use for it, it’s biggest value is in Ultra League, though it doesn’t really get a lot of use there either with all the options you have. It’s a pretty shiny though, and shadow version needs xl!

Being double weak to rock makes this a no brainer, they just out class the other options, Mega Tyranitar and Rhyperior are staples in rock, trade for one of those, I might have said that a few times…
