Seed Sower

Seed Sower is a reactive terrain-setting ability introduced in Generation 9 that automatically transforms the battlefield into Grassy Terrain whenever the Pokemon possessing it takes damage from an attack. This activation occurs regardless of whether the attack deals significant damage or minimal chip damage, making it a highly reliable way to establish terrain control. The ability triggers on any damaging move that successfully connects, including multi-hit attacks, though it will only activate once per instance of being hit rather than on each individual strike of a multi-hit move.

The competitive implications of Seed Sower are substantial, as Grassy Terrain provides several powerful benefits including healing all grounded Pokemon by 1/16 of their maximum HP each turn, boosting the power of Grass-type moves by 50%, and reducing the damage of Earthquake, Magnitude, and Bulldoze by half. This makes the ability particularly valuable for pivoting strategies, as switching in the Pokemon carrying Seed Sower can immediately establish favorable terrain conditions for the team.

Arboliva serves as the sole possessor of this ability, and its Grass/Normal typing synergizes well with the terrain it creates. The combination of passive healing from Grassy Terrain and Arboliva's naturally bulky stats makes it an effective defensive pivot that can consistently provide terrain support while absorbing hits that would otherwise threaten frailer teammates.
