Shaymin (Sky Forme)

While Shaymin - Sky Forme spent a very long time as an extremely mediocre Pokemon due to its reliance on Hidden Power to have a Grass Type Fast Move, the September 2023 moveset update smiled on it in a big way by giving it one of the best Grass Type Fast Moves in the game; Magical Leaf. With this move, Shaymin - Sky Forme's raw power skyrocketed, to the point where it's very much a viable Grass Type attacker.

In terms of viability, Shaymin - Sky Forme is a bit of a situational pick. It's exclusively good as a Grass Type, and in that niche it has the advantage of absolutely WRECKING Ground Types. However, it also has to be a bit careful of anything packing an Ice Type coverage move that will take it down almost instantly. In this regard, it's a situational but powerful pick if played to its advantages... it's just unfortunate that Kartana exists and takes the wind from its sails 90% of the time.

Now we just need Niantic to fix the needlessly weak Seed Flare...
