As SilentVerse said, Lanturn looks very promising in the new meta! And people please don't run the Heal Bell + 3 attack set if you want a good counter to the special fire types such as Magmortar and Moltres (both can 2hko with entry hazards), and to many other special attackers such as Manectric and Omastar, since Lanturn's lack of reliable recovery can only get him so far... Use either the RestTalk set with Heal Bell + Scald/Discharge, or the RestTalk set with dual STABs and Heal Bell support.
And Druddigon seems really interesting right now. The set that i want to use is the Max HP/ Max Atk +, with SR / Outrage / Fire Punch / Sucker Punch, Sheer Force and LO. It has great bulk, nice resistances, only 1 relevant weakness, awesome firepower, perfect neutral coverage, can use LO without the recoil when using Fire Punch (which is a very good attack to spam, as the best switch-ins to him are Steels and Tangrowth), has good utility (SR) and strong priority! What's not to love?

so it's basically counting on a coin flip even if it predicts the switch to Camerupt.
Magmortar has to rely on a coinflip to 2hko Camerupt, not to survive. If your first FB connects, then you stay in and have a 70% chance to kill Camerupt, meaning a 30% chance to die. If your first FB doesn't connect, then you simply switch out and live to fight another day. So Magmortar has 49% chance to 2hko Camerupt, and 30% chance to die from Camerupt.
Magmortar doesn't have so much problems switching in, as you make it seem Honko. First of all EB is way better than LO, as Magmortar already 2hkoes everything relevant with Modest and EB, as he has great super effective coverage, and he also hates the LO recoil. He also has good special bulk and an exceptional ability for this meta, which allow him to easily come into Tangrowth, Roselia, Smeargle, Cryogonal, Lilligant (most of the times) and Ferroseed. Just make sure that SR is off the field, and you can be sure that Magmortar will be coming more than once in each game to wreck havoc!
