>>28632432There's nothing wrong with having lots of legends, but it's not a good idea when the dex is so small. Generally it's a good idea to have 190 mons minimum (this is how many gen 1 was planned to have).
Also this may just be my Sinnoh fanboyism talking but perhaps you could replace the XYZ trio with Dialga/Palkia/Giratina. It makes more sense lore-wise since Arceus is in the dex.
