So from what I see after having played decently intensively for a few days, observing people using Top Lel and playing against this monstrosity:
- It hurts. Oh my god it hurts, and it hurts so bad. The typing of Psychic and Fairy means that if you're running a dark type to soak up the psychic move, you're exposing yourself to get spanked by the Moonblast. Of course, this would probably be null and void if it's Specs Lele (Which from what I gather/have seen is the most common variant) and you correctly predict the move, but then again they can probably also predict your switch and hit you with something neutral off that huge special attack stat. Anything that isn't Blissey or Celesteela can't safely switch into this thing, and the latter case isn't a safe switch if Tapu Lele is running Thunderbolt. (Considering that Celesteela is the new and improved Skarmory as a steel/flying with access to Leech Seed and Flamethrower of all things, and a consistently powerful Heavy Slam, I guess it isn't even a bad option.)
- Psychic Surge partially renders one of its theoretical main counters null and void- a Bullet Punch to the face. Because of Psychic Terrain nullifying priority moves, Mega Scizor is just... Ugh. A consistent counter ends up being an abject failure because of this. Of course, this still leaves Megagross, who possesses resistances to both of Tapu Lele's STABs and decent special bulk to handle neutral stuff being thrown out, but who can be easily walled by Celesteela and Gliscor if Megagross isn't running Ice Punch. So while yes, specifically Tapu Lele can be countered, Tapu Lele also has teammates to giggle madly at those counters as they push them away.
tl;dr: Hits very hard, great STAB combination, Choice Specs set murders anything it looks at that isn't Blissey and often requires sacrifices to deal with properly, Psychic Surge is incredibly problematic.
