Since other people are posting their opinions and experiences with Home in this thread, I might as well share my own.
Regarding Home on the whole, I have mixed feelings about it. I like the base concept of having extra storage for the games, as well as being able to use the GTS and Wonder Trade (though having them exclusive to a side-app is a mixed bag). I really like how Home has a free version, allowing you to use many of its features without having to pay (unlike Bank/Transporter, which only had a paid version). However, using Home can be very inconvenient. Since you can't have the mobile and Switch version open at the same time, and since there are some features which only exist in one version but not the other, it means you have to alternate between them. As for the National Dex, I think this just further proves that removing the National Dex from the games and putting it in side-apps instead was an
awful decision. I have written some more in-depth thoughts about Home and the way it features the National Dex in an old post which can be found
here.
As for my experiences with Home... there's one thing I really want to talk about. I guess I should have posted this back in June since that's when it actually happened, but better late than never.
Ever since it was first revealed that you could get an OC Magearna for completing the National Dex in Home, I had been interested in doing it. But I never got around to it in the past. Mainly due to the awful way the National Dex works in Home, forcing you to actually deposit every single Pokémon in Home in order for it to register them. Compare this to how it is done in Bank, where it just automatically adds the Pokédex data from the games you have connected (which isn't perfect either, but way less tedious). However, completing the National Dex in Home was something I often thought about doing. I was also interested in trying to do it without paying, inspired by
a challenge by QuentinQuonce, who successfully did it in the past.
When Home and ScaVio became compatible earlier this year, I went back to Violet to complete my Paldea Dex. With transfers from Sword, Legends and Go, as well as using the GTS, I managed to register all of the Pokémon I was missing in just a few days. I also got my hands on Walking Wake and Iron Leaves, but it was not easy since those were highly valued. The "Home economy" has always been weird (though I suppose that's mostly a negative about the Pokémon fandom rather than Home itself, or the GTS). It also seems to have grown worse over the years. When I traded on the GTS back then, just a regular shiny wasn't enough to get what I wanted in some cases, which was almost shocking. Either way, I got both of these elusive Paradoxes after a while, as well as all the Scarlet Paradoxes with an English game origin, which was something I really wanted as well. Before I was done, I also added several more entries to my National Dex in Home by depositing Pokémon from Violet.
After this, I was supposed to be done. But I couldn't get my mind off the National Dex and the Magearna. With all the Pokémon I had added from Violet, and all the ones I had added from Sword and Legends in the past, I was only missing around 140-170 Pokémon in the National Dex. Could I actually complete it all without paying? Between Sword, Legends, Violet, Go, the GTS and Wonder Trade, I should be able to obtain most of the missing Pokémon... except for the Mythicals. They are required, and they can't be traded on the GTS, making them a huge block. I could just try and ask other players to let me borrow them just to get them added, either here on Smogon or on some other Pokémon site. But it felt so convoluted.
What was the other alternative? To do it the simple way and just pay for Home Premium for a month. That way, I could get everything I was missing from Gen 1-7 added instantly, while everything I was missing from Gen 8-9 could be obtained through Sword/Legends/Violet. I wasn't sure how the dex entries would get added with Bank, but I looked it up and found out that you just had to transfer one box to Home, then all dex entries from Bank would be added to Home. Seemed simple enough.
I thought it over, and since I value time more than money, I decided to do it that way. It is basically a "pay-to-win" situation, which I can't say I like. Some people claim that Home is overpriced, and maybe they are right, but after checking the prices for Home Preimum, one month wasn't all that expensive (to me at least). So I paid for one month of Premium, connected with Bank, sent over a box of random breeding leftovers, and the first part was over. Since I had all 807 Pokémon registered in Bank, everything from Gen 1-7 had now been added to Home.
I was still missing around 20 Pokémon from Gen 8-9 though. All of them could be caught in Violet, except for one - Nickit. I was too lazy to go back to get one in Sword, so instead, I got one from the GTS for a Froakie (which was along the Pokémon I had sent over from Bank). I then went to Violet and got the rest there, deposited them in Bank and... 1010 Pokémon registered! I had my OC Magearna!
I didn't take a photo of it when I got it in Home, have an image from Violet instead.
It will not be just a trophy as I'm planning to train it for a future legendary/mythical team once the Indigo Disk has been released.
I guess that's my thoughts on Pokémon Home. It works, and it has some good features... but every time I use it, I am reminded of how awful it is. Looking back, I think that it was a huge mistake to make generations transfers require an online connection. Making the National Dex exclusive to apps was a
terrible decision. And Home is
the reason dexit is so awful in the first place.
Now I have finally gotten this off my chest. Thanks for reading.
