Because there's so much fucking retarded misinformation being spread around by complete faggots who haven't even played the games, I thought I should do us all a favor and explain how the new IV and EV training shit works and why it is BETTER THAN GEN 6 when fully understood and maximized.

The TL;DR: edition:

IVs:
>To Hyper Train, you need a Bottle Cap and a Pokemon at level 100
>There are two types of Bottle Caps, one which max out one stat and one which maxes out all stats
>Hyper Training doesn't actually set IVs to 31, it instead sets a flag that makes the game treat all IVs as 31, meaning that the ORIGINAL HIDDEN POWER IS KEPT
>In other words, a Hyper Trained Ditto is not a 31 IV Ditto and will use the old imperfect IVs when bred
>Bottle Caps can be obtained by trading Red/Blue/Green/Yellow Shards with a guy at the Festival Plaza. Shards can be obtained from the Pelago.
>"hurr durr no blissey bases how do I get to level 100" - Levels can be raised using most of the same features that raise EVs (Plaza, Pelago) described below

EVs - The Poke Pelago (PASSIVELY TRAIN EVS WHILE YOU SLEEP OR DO SOMETHING ELSE)
>At the third and final upgrade, Isle Evelup has 3 groups. Each group can have up to 6 Pokemon each and each group can focus on training one stat at a time.
>WITHOUT Poke Beans, each group gains 4 EVs every 30 minutes (8 EVs per hour or 31 and a half hours to max a stat).
>WITH Poke Beans, each group gains 4 EVs every 15 minutes (16 EVs per hour or 15 and a half hours to max a stat).
>You can set the precise interval you want to train if you want to reach a specific final EV.
