Xatu

Xatu is a stylish Pokemon with little to offer. It’s best quick move, Air Slash, doesn’t present any utility in the current meta. Future Sight is a good move, but Xatu lacks the sustainability for a one bar charge move, as well as a quick move that synergizes with it.

Xatu has many weaknesses as well; Rock, Ice, Electric and Dark-types all perform well against it. There isn’t enough power behind this Pokemon to be effective.

Best PvE Offensive Moveset

• Air Slash is superior to Feint Attack for raw power and STAB.

• Future Sight is a powerful move and ideal on Xatu due to STAB.

• Aerial Ace is slightly more powerful than Ominous Wind, but Ominous Wind’s Ghost-type effectiveness can be useful.

Best PvE Defensive Moveset

• Air Slash does more damage, but Feint Attack has coverage against Ghost-type. Both can be considered.

• Ominous Wind is slightly superior to Future Sight due to low charge time and counter coverage.

• Aerial Ace can be considered for its damage potential due to low charge time.

• Future Sight is not suitable on Xatu due to its poor defensive stats.

Air Slash and Feint Attack are both mediocre options; the former benefits from STAB while the latter provides coverage. 

Aerial Ace benefits from STAB, and while not the most efficient charge move, is the most accessible. Ominous Wind can still be used for its coverage, despite being nerfed following the April 2020 rebalance. Future Sight deals the most damage with STAB, though 65 energy is a lot to ask for.
