Hoopa (Unbound)

Hoopa Unbound possesses an absolutely massive 311 base Attack stat, surpassing even that of Mewtwo. However, its performance in raids is merely good instead of top tier. As a Psychic-type attacker, it trails slightly behind Mewtwo in DPS, as it doesn't have access to Mewtwo's devastating Psystrike. Furthermore, its Dark secondary typing removes the useful Fighting-type resistance. As a Ghost/Dark-type attacker, it is held back by Astonish's poor parameters, and Dark Pulse being only as good as its unSTABed Shadow Ball.

All hope is not lost for Hoopa Unbound however. Its Psychic/Dark typing provides it with near immunity levels of Psychic resistance, giving it an incredible staying power against some Psychic bosses. Furthermore, Hoopa Unbound's signature move, Hyperspace Fury, is currently in the game's move list. While we don't know its stats yet, Niantic has often been generous when it comes to signature moves. If the move is at least as strong as Shadow Ball, it will immediately propel Hoopa Unbound to a top tier attacker even with Astonish's underwhelming parameters.

Basically, Hoopa Unbound is a solid choice for an attacker, just not quite top class YET.

Best PvE Offensive Moveset

• Confusion should be paired with Psychic to make Hoopa Unbound a powerful Psychic attacker
• Astonish can be paired with either Shadow Ball or Dark Pulse to make Hoopa Unbound a strong pick against Psychic- and Ghost-type raid bosses

Confusion is the superior fast move simply by having far better parameters than Astonish.

Dark Pulse is Hoopa Unbound's cheapest charge move and benefits from STAB. Psychic is a powerful STAB move, although it doesn't provide much additional coverage. Shadow Ball is a great move, but its coverage is largely redundant with Dark Pulse around, and Psychic covers for Fairy types anyways.
