Mid-stage Pokemon like Marshtomp rarely see competitive play outside of special formats. It's a waypoint on the road to Swampert, which is where the real potential kicks in. Known as the Mud Fish Pokemon. Can go either physical or special depending on the set.
Attack and HP carry most of Marshtomp's stat budget. Speed's the obvious dump stat. Tough to catch and yields 2 Attack EVs. Follows a 1.06M XP medium-slow curve.
The surface of Marshtomp’s body is enveloped by a thin, sticky film that enables it to live on land. This Pokémon plays in mud on beaches when the ocean tide is low.
Marshtomp is much faster at traveling through mud than it is at swimming. This Pokémon’s hindquarters exhibit obvious development, giving it the ability to walk on just its hind legs.
Marshtomp Weakness
GoodMarshtomp's Water/Ground typing leaves it vulnerable to Grass moves. Grass hits land at 4x, so they're the biggest threat. It shrugs off Electric-type attacks completely. 4 resistances help offset the weaknesses.
Partway through Mudkip's chain. Marshtomp still has another evolution ahead before reaching Swampert. For breeding, average hatch time with no compatible partners via two egg groups. So far, HP got the biggest boost (+20 from Mudkip). The final form adds another 130 stats on top.
How to Evolve

Marshtomp is meant to evolve into Swampert. At 405 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.
Torrent strengthens water moves to inflict 1.5× damage at 1/3 max HP or less — that's the one you want on Marshtomp. Damp is the hidden ability. Niche, but it has its uses.
Base 50 Speed is low. Priority moves or Trick Room are the way to go. On offense, Marshtomp is a physical attacker with base 85 Attack. Defensively? Enough bulk to take a hit or two.
