Intro

Gliscor
We already have Landorus, but Gliscor can do a number of things Lando can't
Bulky - Poison Heal and Roost
Offensive - similar to Landorus with its typing, with similar STABs and access to SD. But slightly different due to Ice Fang and Hypercutter
Additionally, Max Quake and Max Airstream combo, access to Dual Wingbeat

Slaking
We already have Regigigas, but Slaking can do a number of things Regigigas can't
lower SpD but higher HP
Access to recovery in Slack Off, plus some interesting utility e.g. Taunt and Encore
But biggest difference is access to Bulk Up so you can boost stats - this is something Regigigas cannot do
Plus Slaking has been bad since its introduction, it would be so refreshing for this mon to see use outside of the Mummy-king strategy

Starters
Serperior - Contrary is fantastic in dynamax metas where max moves tend to drop stats, plus pair with Eerie Impulse Regieleki for fast SpA boosts BUT loss of HP means it has v bad coverage now
Empoleon - potentially gets Flip Turn which could make it great utility in singles with Defog to remove hazards, or for momentum on offensive sets. Steelspike gives it great bulk and offense.
Greninja
Popular
Protean - we only have Libero so far on physical Cinderace. Greninja is faster and is a special attacker which is important - not affect by Intimidate and could be very strong with its coverage
Max Darkness drops special defence

Oricorio
Random, but I think its super underrated
Dancer
Max Airstream
Different forms

Minior
Max moves
Shell Smash option
Can't be statused in meteor form to take on Venusaur for e.g.
Meteor Beam

Murkrow
biased
Tailwind - already have options
can't be taunted
STAB Foul Play
Quash
Taunt, Feather Dance, Thunder Wave
Mirror Move, Perish Song
