Requires Trick Room & Sun set up to work. Exeggutor's low Spe can help it outspeed other Trick Room mons like Ursaluna. Harvest w/ Petaya Berry in the Sun lets it constantly grab a free +1 SpA. Flamethrower and Solar Beam get boosted in the Sun and are great Offensive options. Note Petaya Berry requires 1/4 HP, and healing like Giga Drain are anti-synergistic. Exeggutor should reach that HP threshold after taking a neutral hit and setting up Substitute.
