Anyone thought about a keldeo drop? With magearna becoming as popular as it is keldeo's scarf set has one of its best answers running around on a lot of different teams. Combine that with the fact that he lets in magearna for free who is arguably the best sweeper right now.
I disagree, and I also don't follow the logic for a drop here either.
Keldeo doesn't really let in Magearna for free - at least not the offensive sweeper sets, like you mentioned:
252 SpA Keldeo Scald vs. 0 HP / 4 SpD Magearna: 115-136 (38.2 - 45.1%) -- guaranteed 3HKO
252 SpA Keldeo Hydro Pump vs. 0 HP / 4 SpD Magearna: 159-187 (52.8 - 62.1%) -- guaranteed 2HKO
252 SpA Keldeo Scald vs. 252 HP / 0 SpD Magearna: 117-138 (32.1 - 37.9%) -- 93.3% chance to 3HKO
252 SpA Keldeo Hydro Pump vs. 252 HP / 0 SpD Magearna: 160-189 (43.9 - 51.9%) -- 11.7% chance to 2HKO
Magearna can't switch into Hydro Pump if it's running the shift gear set, and it can't even switch in into Scald and beat it with SG + Thunderbolt either. Even if you both get sent in at the same time, Keldeo clicks Hydro Pump to 2hko the Shift Gear set. The OTR set is more reliable, but you're still taking a chunk of damage if you switch in to something besides Scald - not to mention the fact that you need to still get up TR if you want to sweep. Plus, this is only the Scarf set - if Keldeo happens to be running Specs, you get 2hko'd by Scald if rocks are up. I'd say that the only set that can reliably beat Keldeo is AV.
And choice specs is pretty bad. So much shit can switch into it easily that I can never see myself using it over ash greninja for a water type wall breaker. While not all Mew's run spdef if they do another answer for Keldeo is becoming popular. Volcorona becoming less popular also makes Keldeo less viable since he was a pretty good answer to it. the Pokemon that were common months ago when it rose just aren't as common now and things that annoy Keldeo have risen so I'd say drop this thing to A-
EDIT: forgot to mention pinsir who shits on keldeo with his priority also becoming more popular since Keldeo rose
I don't get how Specs is bad? You don't really do much to justify that argument. The fact that 'so much shit' can switch into it applies to pretty much any choice locked mon, and looking at S through all of A rank, the only things it doesn't hit neutrally with its stab are Tapu Bulu, Toxapex, Amoongus, and Latios. Add in the fact that you have to predict whether it's going for a water type or fighting type move and really, not a lot of things are switching into it easily as you stated.
I also don't understand why people feel like they need to pick between Ash-Gren and Keldeo. They both form an amazing double water core who help break each other's counters very effectively and using them both on the same team really isn't bad, so I'm not sure how that bolsters a Keldeo drop.
"While not all Mew's run SpDef if they do another answer for Keldeo is becoming popular." What? Mew runs PhysDef because it's able to check and cripple a lot of things like Mawile, Zygarde, Medicham, Garchomp, etc.. so I don't see the point in stating that. Charti Berry Volc became a good answer to teams who solely relied on Keldeo as their Volc answer and the fact that its viability is decreasing potentially opens up that last moveslot for HP Electric. Pinsir is a solid answer to it, but that's like me saying that both regular and mega TTar have risen in usage, who Keldeo happens to destroy.
Also another thing going for it is that it is pretty annoying for rain teams to face.
I can't see Keldeo dropping for the time being, or at least not for the reasons stated above. It's still a great offensive mon capable of running both Scarf and Specs and its stab are not as easily abused as other scarfers like Chomp/Terrak.
Keep Keldeo in A.
