I remember being a massive proponent of MC back in BW. I understand that over a generation and a half, a lot of things will have changed, but I have a couple of things to note:
Lampent is going to be really good. It's a full stop to Combusken. One of my brightest memories of BWMC was how everyone lost their marbles over Combusken until we clued in that Lampent is the answer. The new BP rules really hinder it too which doesn't say much. Lampent's not as offensively great as Haunter, sure, but it's a more defensively reliable Ghost-type (not Dusclops-esque, but for a more offensive team, it's very welcome).
Don't sleep on Klang. Shift Gear was a menace in BW, and I don't see that changing. It's got stiff competition in the form of Doublade, but the speed boost is very handy, especially in the late game. Why resort to a 40BP move to outpace things when you can simply outspeed them?
I'm surprised Dusclops is considered as good as it is, even despite the buffs to Knock Off. Regardless of Eviolite being banned, Dusclops does not appreciate having Leftovers removed. Is there a lack of users, or is Knock Off not being paid any attention to?
On that note, why in the blue hell is Machoke D-Rank? No Guard Dynamic Punch? Knock Off? It's got a hair more special defence and speed at the cost of a hair's worth of attack, HP, and defense. In terms of Guts, yes it's handily outclassed, but it has such a diverse movepool. The Elemental Punches, Heavy Slam (for the Faries), like Machoke has it all. Am I missing something?
