Definitely disagree with a keldeo drop, for me the set ive had the most success with is sub cm w lefties. This lets keldeo act not only as a massive threat to plenty common stall archetypes in the current meta that opt for mons like mega aggron, buzzwole, quagsire, etc in order to check the mega mawiles and zygs that dominate this tier, but also keeps it decently healthy so it can act as a response to the threat of mons like heatran with the passive recovery. Sub makes keldeo harder to revenge kill as the waterium taunt cm set has the issue of no passive recovery meaning it gets worn down and you have to worry about them making a potential switch into a faster mon like kart/koko as you taunt a toxapex that could otherwise toxic you and end keldeos longevity. It should be noted that after you knock off pexes black sludge sub cm keld does in fact beat pex 1v1 so it has that going for it and keldeo pairs well with a lot of common knock users in the tier including but not limited to tornadus therian, weavile and mega scizor. Finally this set has the potential to cripple bulu for the rest of the match making it a truly insufficient check to mons like subcoil zyg which bulu could otherwise beat by running attack evs as well as say mega alakazam as its passive recovery upon switchin will be partially negated. In addition the grassy terrain benefits keldeo by healing it 12% per turn which can help to negate magma chip from heatran and you can even make low risk high reward plays like sub up vs the bulu to try and catch a potential double and only lose 12% of your hp if you get the play wrong while getting 2 chances to burn the bulu if you get it right and force them to take hazard chip.



Also I agree with a ferrothorn drop, it does not beat zygarde well at all compared to other grasses, ash grens pulse does a sizable chunk and then you're forced to either whip to try and kill the gren if they potentially stay in and fish or predict a telegraphed leech seed or go for said leech seed in an attempt to heal urself vs an incoming foe. Opting for max spdef and forgoing all that defense makes it super vulnerable to mega swamperts earthquake and the occasional superpower for kartana will just smash it. Mega mawile and heatran, two of the tiers most common and most threatening breakers abuse ferrothorn easily and you see less tapu koko in the meta and other electrics instead like washtom which can wisp it or zapdos which obviously stops ferro.



Zapdos B+ -> A-



Speaking of zapdos this thing is pretty undervalued i feel, a 3 attacks set is lethal as shit when you consider how less usage clefable gets thanks to the aforementioned mawile and heatran and most teams ways of dealing with electrics in general involves a ground and a grass type and the most common grounds in ou zyg/lando/chomp/glisc all get bopped by hp ice and grasses take a significant chunk from heat wave. This thing is also one of the best if not the best answer to that bullshit mon tornt this meta has to offer. Pressure and static make it a customizable mon as you can use it on stall with pressure to stop rockers or use static as a means of speed control for slower breakers like mawile and heracross, volt switch can even be used on it to grab momentum.



Mega Venusaur B -> B+



Another undevalued mon rn i feel, its a fairly customizable mon that takes on a lot of threats in this meta like bulu, mawile, kartana, swampert efficiently with a max phys def set and although im not a fan of spdef you can for sure use it as a agren check when paired with a dark resist but it is a stellar magearna counter and also solid heatran lure as sludge bomb into stomping tantrum straight ohkos and you dont have to worry about eq damage being weakened by terrain. However like ferrothorn it does have the problem of being a mediocre check to agren and zyg tho phys def can handle certain zyg sets decently well and it does a hell of a lot better job than ferro. Its also one of the best answers to serperior and the aformentioned bulu and again usum has brought us a lot more foggers to choose from so getting off spikes is easier for this thing and you see fewer rain teams and av ttar is not forcing out venusaur anytime soon with that little attack all which aid its mediocre recovery option synthesis.



Post was all over the place as i gotta go real soon but wanted to get this out but basically kelds fine where it is, drop ferro and bump up venu n zap
