Lanturn

Lanturn's coveted resistances to common offensive types such as Fire, Flying, Ice, and Water, as well as an immunity to Electric, grant it the unique ability to wall powerful threats such as Magneton, Fletchinder, and Emboar. Its slow Volt Switch allows frailer teammates to switch in without fear of attack, and on top of this, Lanturn packs STAB Scald to ward off Ground-types that may want to block Volt Switch or even just physical attackers that may want to set up on it. Lanturn can further support its team with Heal Bell, and unlike other clerics such as Aromatisse, it does not necessarily sacrifice momentum to do so.

That said, Lanturn is held back by middling Special Attack and Defense stats. It is very easily worn down due to its lack of recovery and vulnerability to all forms of entry hazards, as it is generally needed to switch into dangerous threats constantly. It is a bit of a liability against Grass-type threats, such as Virizion and Shiftry.
