Fair point. And if you don't attack with it, why are you posting this in the OPENING POKEMON ARTICLE?
Because it doubles as an opening pokemon as well. Togekiss decks for instance have this irratating tendency to have HORRID opening hands. Chatot can help get around that, unlike Baltoy whose Psychic Balance is rarely being used because of the dependency on the ability to decrease your hand size first.
A starter who's actually useful mid-game as well is probably worth mentioning. Is it a safe starter? Compared to stuff like Phione, not really. But does it have several unique aspects? Yeah. Sounds like its worth mentioning at least in the article.
I don't know if I'd agree with Pachirisu being outdated. It's like saying Tauros is better then Pachirisu; Call isn't 100% better then Pachi. Are there decks that want three pokemon on the bench, ready to evolve next turn? Yeah. Magmortar comes to mind, as does Skittles. Those decks probably want Pachirisu more then they want Call Energy. :/ Getting three pokemon over getting two can make a difference. ...Plus, the whole "Pachi is searchable" stuff too. It's not like Corsola who's beaten in EVERY WAY by Pachirisu (except for the Fighting Weakness, assuming someone figures out how to make Kabutops good <_<").
Stantler's name is mispelt for some reason as Stanler. Hm.
I noticed that the Mawile section doesn't mention the Turn1 Cessation Crystal that's ensured with Mawile. Hm. After all, being able to attach tools directly to pokemon with Mining... Just... Might be a good reason to consider it over Stantler :/ It's a bit better then Lapras in a Lock Deck, since Lapras doesn't attach the Tool right away. (plus the colorless energy cost, rather then water)
Bit surprised that Lunatone/Solrock or Rotom aren't mentioned. I guess Rotom's more of a recovery guy then a starting pokemon, but Luna/Sol's fairly nice for setting up certain decks (Garchomp <_<).
