Lanturn

Lanturn's excellent typing makes it only one of three ADV Pokemon that resist both parts of the BoltBeam combination; it is also the only one with any defenses to speak of. Thanks to its has good special bulk, excellent type synergy with Pokemon such as Skarmory and Gyarados, and ability to spread paralysis, Lanturn is a decent choice for standard teams. In addition, Lanturn is one of the few Pokemon that can effectively stop offensive Calm Mind Suicune, who is a huge threat that many teams have difficulty dealing with.

However, without large investment in Special Attack, Lanturn lacks firepower. It suffers from a crippling weakness to the very common Ground-type attacks, and its lack of phazing capability leaves it setup bait to the likes of Calm Mind Celebi and Curse Snorlax. It is also vulnerable to all forms of passive damage, and hates poison unless it is running a RestTalk set. Nonetheless, its glut of resistances and immunities to common attacks, along with its good bulk, makes it a worthwhile addition to most teams that need a bulky Water-type.
