This is a very solid list that i mostly agree with. Here are the few i disagree with:
Victini from B to B-
Sure victini has the excellent movepool, good speed tier u turn etc. but it has weakness to stealth rock and pursuit and could do nothing against tyrnaitar, one of the better pokemon of the tier. It also usually gets stuffed by heatran. Sure it has its niche but i feel it is a very small one.
Mega Charizard Y from B- to B+
Ok this might be a bold statement but i feel mega charizard y isnt that bad. Sure it has the terrible 4 times stealth rock weakness but keeping rocks off the field is worth it for this monster. Fire blast does mind boggling amounts of damage in sun and has excellent coverage in focus blast for ttar and solar beam for waters in sun. It has the prized 100 speed tier. Additonally, defoggers in lati twins could function well along side it and you could make agressive double switches into charizard Y to avoid getting pursuit trapped (or defiant boosted from defog) by bisharp. It is a high maintenace pokemon but it works very well when played correctly.
Jellicent from B+ to B:
Other than stuffing volcorna and keldeo (although not completely). It doesnt have any other niche. Its special defensive profile is not enough to make it work against the pursuit trappers running around. It also is set up father for mega charizard X and struggles with serperior. It is solid in the metagame and is a great pick, but it is too flawed to stay in the B+ tier with monsters like latios dragonite and zapdos.
Mega Alakazam from A to A-
This thing has no bulk and could only come in on pivot moves. It depends on focus blast to deal with pursuit trappers (super unreliable). It also loses magic guard when it becomes mega so it would be worn down by hazards when it switches in. t struggles against fast scarfers and revenge killers. It is basically the definition of a glass cannon, a unreliable glass cannon of that. It also loses to all physical pirority. Despite having a insane speed tier, its flaws justify a lower ranking
THATS IT
Thank you for coming to my ted talk
