Tropius

Tropius is not the Exeggutor you were hoping for. It has an okay moveset but cannot survive due to Flying and Grass-type being a particularly vulnerable pair. 

Best PvE Offensive Moveset

• Razor Leaf can be paired with Leaf Blade for Grass-type coverage.
• Similarly, Air Slash and Aerial Ace are paired for its relevant matchups. Both pairs are similar in terms of damage output.
• Stomp has no utility on Tropius. 

Best PvE Defensive Moveset

• Razor Leaf and Leaf Blade can cover the Rock-type weakness.
• Air Slash and Aerial Ace can provide some extra Machamp hate.
• Stomp can take a hard pass.

Air Slash is the generally more preferred pick, having a balance between damage output and energy generation, and is better at fueling Tropius's good Charged Attacks. Razor Leaf Tropius was a staple on Razor Leaf spam teams, but its nerf starting from Pokemon GO: Max Out has made it considerably less potent.

Leaf Blade solidifies Tropius as the Banana Blade of the Sky thanks to its cheap cost and high DPE. Brutal Swing gives coverage against Pokemon that resist Leaf Blade, most notably against Steel-type Pokemon. Aerial Ace is not absolutely necessary but does help Tropius with some form of coverage, and also gives it an advantage against other Grass types including the Tropius mirror.
