Presumably this is because it is a One-Hit-Point Wonder who usually relies on its invulnerability to all damaging attacks that aren't super effective against it to survive, and without that ability it SHOULD be a sitting duck.

If the Invincible Shedinja trick note Having a Carbink with Sturdy use Skill Swap on a Shedinja who has had its ability changed for whatever reason, such as being hit by Simple Beam or Worry Seed is successfully pulled off, the AI will attempt to target the Shedinja at every possible opportunity.

As such, the AI cannot make complex predictions on the type changes and is easily played around. The ability changes the user's type right before it attacks, but the AI makes its decisions based on what the Pokémon's type and what it thinks its stats are before Protean takes effect.

The in-game AI has considerable difficulty dealing with the Protean ability.

Her Rhyhorn is even outside the player's house, and it's known the player since they were born! Professor Sycamore chose them to help him out because he heard that she had just moved into the region.

Action Mom: The player's mother, Grace, is a former Rhyhorn racer, instead of just a homemaker like previous versions.

Abandoned Playground: There's one in Route 14 just north of Lumiose City, though it's in very good shape.

You can also go beyond what previous games (and Omega Ruby and Alpha Sapphire themselves) consider 100% completion by collecting Gen VI-native specimens of each Pokémon in the three Kalos regional dexes, earning a crown symbol for each dex you fill this way (the crown appears beside the National Dex just for collecting every Pokémon, no matter where they originated).

This was only possible with Pokémon Bank before Omega Ruby and Alpha Sapphire came out now it is possible with just these four games, which is also a first in the series. There is no reward for capturing all of the Kalos region Pokémon, but the reward for capturing all Pokémon in the National Pokédex (excluding some special and event Pokémon) is the Shiny Charm, which increases the chance of encountering shiny Pokémon.

100% Completion: Seeing all of the Pokémon in the Kalos region (minus the two Legendary Birds you won't get to see) rewards you with the Oval Charm, which makes eggs show up much faster at the Day Care.
