braviary isn't the only thing you should be looking at when considering bastiodon. lairon can do the same, and all bastiodon has over it is more special bulk. you have to consider: how does bastiodon fare against the rest of the tier? how well can it perform its role (especially in comparison to other stealth rock setters)? it does okay, but the thing holding it back is the lack of offenses and the presence of strong fighting- and water-types in the tier. anyway, i agree with sawk being s-rank. pretty much exactly what flcl said: plus the fact that it has a neat base 85 speed and the ability to OHKO so many things means that it doesn't always need to get things on the switch. sawk forces many teams to pack a resistance, if not a ghost-type or alomomola (who struggles with sawk anyway). as for ampharos, i think the thing holding it back is its speed. it looks fairly bulky, but the fact of the matter is that it's worn down as a defensive pokemon. offensively, it's neat because it's pretty strong and all, but again it gets worn down due to its low speed in comparison to the electric-types aforementioned. i think b-rank is already fitting; ampharos has many options in its movepool but i don't see it excelling at one of them in comparison to something else that's in the tier. i want regice to be discussed more before it's placed into s-rank. it may seem like an s-rank pokemon, but it's really pressured by hazards. people have been utilizing rest + sleep talk, but once you use rest, you're going to have a hard time spending three consecutive turns to use it again to gain your hp back if the opponent is competent enough to keep it pressured. in addition, using that set means you're foregoing focus blast and thunder wave which would be amazing so that regice can hit piloswine and rotom-f much harder while catching things like emboar on the switch with paralysis. regice puts a stop to many special attackers, but it still doesn't excel as well as it should against the best. think about ludicolo: regice cannot beat ludicolo one-on-one if it switches in on stealth rock and as ludicolo uses rain dance. my experiences using regice has been generally positive, which makes it a great candidate for a-rank. however, the fact that it suffers a bit from four moveslot syndrome and stealth rock weakness holds it back from s-rank in my opinion.
