It's hard enough to get a Shapeshifter, but getting a useful Shapeshifter with high IVs is hard. IVs are the “genes” of a Pokémon, and you can check them out after defeating the main story. Max IVs is what you're aiming for, and Max Raid Pokémon will rarely have 4/5 Max IVs. The more Max IV a Pokémon has, the better it is for reproduction: it will pass these values on to its eggs.
And there is no better Pokemon for breeding than Ditto. It can spawn with any Pokémon in the game, and it's worth farming for hours to get a good Ditto. Here's where to find one.
How To Catch Metamorph | Max Raid Location
There are a lot of Pokémon to catch in Max Raids, but Ditto is one of the most important if you want to create a lot of Pokémon. Ditto has no gender, so he can spawn with any other Pokémon in your Pokedex. The trick is simply to find a Pokemon with awesome IVs.
To find (and farm) for Ditto, you need to have access to the Outrage Lake Wilds. You will unlock the possibility of crossing the water with the bike Route 9. The den you are looking for is the one surrounded by mysterious standing stones in a circle.
This denier Max Raid is where Ditto can spawn, and you'll need a lot of Wish Coins to spawn it. You can find Wishing Pieces by chatting with the Digger Bros (Digging Duo) in the Wilderness - they can be found to the right of the Pokémon Nursery.
In exchange for 500 watts, they will collect random rare items for you. Speak only to the brother on the right - He digs less, but he can find the wish piece. The brother on the left won't find him no matter how good he looks.
When trying to catch a Metamorph, make sure you are the Host. The host of a Raid Max will always catch the Pokémon - there is a 100% chance. You can do this by choosing to stay on a local connection and not inviting other trainers to help you. I also recommend that you make sure you do this early in the day. So, if you are farming (and fail), you won't be able to perform a midnight reset. All Max Raids reset around midnight.
