just jotting down my thoughts:
I feel like
Larvesta and
Ponyta both belong in
A. They're both great counters to most Fighting types, and both have their advantages and disadvantages. Ponyta is fast, Larvesta has the Bug-typing and most importantly, it has access to U-Turn, which amazing on a mon such as Larvesta.
I'm in support of moving
Mienfoo to S-rank. It performs very well with great consitency as mentioned before, and it checks/counters a large number of threats in the current LC.
torchic to A torchic pass is broken as fuck (watch
corkscrew vs artemisa if you're not convinced). Since torchic is the focal point of these teams, it should be A
scraggy to A Scraggy's Dragon Dance set remains amazing despite Spritzee being quite common. A lot of Mienfoo don't run as much bulk as they used to do, which means +1 High Jump Kick does a ton, and +2 (pretty easy to get to if using Moxie) always OHKO's. It's also an amazing user of Knock Off, being able to come in early, Knock Off it's own counters, and sweep later on.
cottonee to B Cottonee is amazing on offensive teams, as it provides a lot of support with priority Stun Spore, Memento, etc. It's also the best Carvanha counter in existence :]
Honedge to B Honedge performs very well both defensively and offensively. Defensively, it's main selling point is walling the shit out of Meditite. It also deals with Spritzee and Fletchling if it's not running any Fire moves. Offensively, it's STAB's hit everything that doesn't resist them hard, while Sacred Sword can be used for cool coverage.
Darumaka in B ohko everything
Lileep to B Lileep does what it did in gen 5, tank hits and recover them off. It counters nearly all special attacking threats in LC, while also dealing with some physical ones such as Drilbur and Murkrow, to an extent. it's also an amazing Stealth Rock setter for balanced/defensive teams.
I agree with Corkscrew that
Slowpoke should be moved down to
B. There's little to no S/A-tier mons which it counters, which makes it nearly useless against most teams
