Poor Doublade didn't rise...
I have nothing to add to it right now, but I still think it should go to C-.
Magnezone for B+:
I want this Pokemon moving up. With less Mandibuzz comes more Skarmory which helps Magnezone ALOT. Steel-types are still very great and having a Pokemon that can reliably kill them with almost no prediction needed is very useful. Teams that are relying on Skarmory as Defogger or Ferrothorn as Hazard-setter have very much trouble to keep hazard under control, Pursuit-Scizor can be lured in with Lati@s and killed safely. It supports the team with eliminating certain threats and still hits hard with a Choice-Specs set or acts as a revenge-killer with the Choice-Scarf set. Definitely a B+ Pokemon.
Azelf for B:
This Pokemon needs a big jump imo. After the ban of Deoxys it is one of the most reliable hazard-setters for HO teams. Access to Stealth Rock, Screens, Explosion, Taunt and even Magic Coat lets it do a similar job like Deoxys. It is in a nice speed tier (better than Deoxys-D) and outspeeds most other Taunters (except Prankster, but Magic Coat can help here). It is definitely not a Pokemon for C-rank, and B- seems too low for me. I suggest B.
Suicune for A-:
Waterabsorb is a rare ability in this metagame, so nothing can stop its Scald-spam. After one CM it can pass through some of its counters (it can beat Mega-Venusaur after one or two Calm Minds) and has probably the best Rest-Talking set in the game. It has also a more aggressive and very underrated set in form of Scald/Ice Beam/HP Electric/CM which can surprise unprepared teams and deal heavy damage. Not many people are prepared for Suicune and therefore it happens very often that you can meet a team weak to it. A great win condition for bulky offensive and a more aggressive option for stall teams. Needs to rise.
Excadrill staying in A+:
This Pokemon is perfectly fine where it is. Sand-Rush versions need Sandstorm support and can be stopped by other weather mons especially Charizard-Y. Even with its resistance to Flying, Brave Bird from Talonflame does a ton of damage. It also kinda lacks in power (135 base attack aren't THAT awesome anymore...) so many physical walls can counter it way too easily (Skarmory, Hippowdon and Gliscor for example, Zapdos can Roost-stall Rock slide if it lacks LO).
The Scarf-set is a great revenge-killer but a bad spinner (never good to be locked in Rapid-Spin) so I don't see any of its sets to be good enough for an S rank. It is not easy to slap on a team like the other S-ranks and needs way too much support to be effective. The rise of Starmie hurts him too since it isn't the only offensive spinner anymore. In short: Great Pokemon, but not S rank material.
