Lore: Surtrifer are capable of carrying even the heaviest Pokémon as long as it is swimming on water surface or underwater. However, their swimming skill also make them very prideful, refusing to change strategy.
Competitive Potentials: Balancing an absurdly huge learnset by an unhelpful Ability, Surtriefer can either be a Sticky Web support, or a powerhouse of a sweeper with a truly massive coverage potentials, such as Glacial Lance, V-create, Blue Flare, Sacred Fire and Steam Eruption. Its Ability, Prideful, means that no, you cannot set up Geomancy or the likes, but the rest like hazards, Taunt, Perish Song, Toxic, Thunder Wave, Entrainment, or if you are willing to risk, Skill Swap, are free game.
This is help back by its frailness and its Ability, which prevent set up sweeping without using Skill Swap firsthand. It is also have average Attack and Special Attack, and is pure Water, which means it is limited to one STAB.
