Base Stats
Looking at its base stats, Tapu Lele has some strong stats for an offensive Pokemon. A 130 base Sp. Attack is fantastic as it allows Tapu Lele to use very strong Special attacking moves, which means that it's certainly gonna show up in the damage department. A 95 speed stat means that while it won't be the fastest Pokemon, it will be fast enough to where it can outspeed many Pokemon in a slower format like this one. Defense wise, 70/75/115 is pretty decent overall as its not frail enough to where it must carry a Focus Sash, but it also isn't bulky enough to where it can just sit on the field and take a ton of hits before going down, so it can take a few neutral hits and still have enough HP to survive the turn pretty comfortably.

In VGC 2014, Gardevoir, a very popular Pokemon, was commonly holding a Choice Scarf. This season, Tapu Lele is taking that role and is doing it very well. This set takes advantage of the Choice Scarf so that Tapu Lele can be as fast as possible and hit as hard as possible. The moveset is designed to hit as many different Pokemon as possible. The dual-Fairy moves in Moonblast and Dazzling Gleam so that you can get a strong spread move and a strong single target Fairy move for various situations. Psychic is standard and the last slot is completely team dependent. If you want to a strong electric move, Thunderbolt is useful, Energy Ball is good to hit Gastrodon, Shadow Ball is good for Alolan Marowak, and Hidden Power [Fire] is good for Kartana and Celesteela so it depends on personal preference.
