I agree on Alakazam getting to A+, at least A, it's just amazing against both offense and balance/stall.
My personal changes:
Conkeldurr C => B-, Conkeldurr is pretty underrated, he is not the best mon ever but the guts/sheer force versions are pretty threatening, C is a crappy rank, B- is decent ( http://replay.pokemonshowdown.com/smogtours-gen5ou-29104 don't pay attention to how he played, but for example on this match-up bulk up conkeldurr was really tough for bloo)
Slowking B- => B, Great Keldeo check, the TR / Sack off+ 3 attack is really good
Hydreigon B+ => A, Hard to switch into, really strong against Sand balance, good typing, not weak to SR / Pursuit, the only flaw is not being a really good check to Keldeo compared to ti@s
Amoonguss B+ => A-, Another great check to Keldeo / Breloom / Rains, not being weak to pursuit is a good. it is also surprisingly frustrating to switch into when you play offense, Spore+Stun spore is annoying. He has an indirect heal as a flaw and doesn't put that much of a threat offensively speaking
Xatu B => B-, the only purpose on playing Xatu is to avoid letting SR tear your sun team apart, and i'd rather play espeon tbh, U-turn being the only good point about Xatu
Reuniclus A- => A, both trick room and cm are troublesome for a lot of teams, the cm can deal with teams like bulkysand with ease and the tr is a good lategame cleaner
Roserade B- => B, slighty worse than amoonguss in terms of healing but spikes/toxic spikes is a huge benefit, leaf storm also pack a real punch
Donphan C => B-, decent spinner in sun and in some rain teams, useful to check mons like dragonite/garchomp who are quite troublesome in suns
