I'm loving this so far based ninja :], but here are some of the things I'd like to comment on:
Garchomp to S Rank
I already had thoughts on this on gen V so I guess I'll use some of my ideas from then: Garchomp is probably the most solid (stat wise) pokemon in OU bar shit like Kyurem B, it has awesome bulk, only facing competition in raw bulk from Kyurem B and lolzygarde as a dragon, it's 130 attack with it's amazing STAB coupled with Swords Dance really makes it hard to switch into, it has one of the best speed tiers in XY OU *for something that has that bulk and power*, letting it revenge a lot of stuff with it's scarf sets and even banded sets. .It has 2 fantastic lure sets in: yache and haban SD chomp. Which beat most ways of revenging it, and it's bulk lets it run both a lead set and an subsalac set. While fairies may have fucked salamence and maybe even dragonite, Gachomp can remain near unscathed. Heck the biggest nerf to it this gen was actually the fucking rain nerf! Now the aqua tail sets are going to either run LO more often or use damp rock on politoed support or scrap politoed/rain altogether. The only 3 true counters to this thing (togekiss, skarm and bronzong) are smashed by the aqua tail set, which now can use it's badass new mega form which I will cover later:

(I honestly believe mega chomp should always be adamant if it's going to SD because it's a great way to abuse the power it was given while saying fuck you to the sped tier the mega puts it in, but I put in jolly calcs because that fact is very debetable)

(left out LO on regular chomp in inside rain calcs because I doubt people would run LO when they have rain, because they could just run a resist berry and be even more check resistant)
This lets garchomp like previously stated, smash it's counters. And if chomp wasn't strong enough, it got a freakin mega! which allows it to run mixed sets, bulky SR sets, wallbreaker, and wall sets even better! all in the exchange for an item slot. The only way to beat this beast is to revenge it with fast dragon or ice moves(or ice shard) and hope it doesn't have a resist berry, Overall garchomp is just awesome and deserves one of these 2 ranks. I also thing mega g. should be in the same rank as I believe seperate ranks in terms of megas should only be reserved form egas like lucario or charX who work like 9x differently or are 9x better than their base form, but that's just imo.
