Dragons are one of the most dominant types of legendary. Okay. They're mystical and ultra-powerful and rare, we get it.
Then there are the birds...cool enough. Ho-oh is my favorite legendary.
And the cats (I refuse to call them dogs). Nice.
Then all the psychic-types. Okay, psychic is a great type. Don't exactly know what they're supposed to be, but okay.
The weather genies. No thanks, but genies are mystical and all.
The swords of justice. They're the Three Musketeers. Terrakion looks a little dopey.
The miscellaneous, like Shaymin and Arceus. Not exactly a group, but they're there.
The legendary golems, which I think are a terrible concept.
So...more random dragons and stuff?
What if for the next sets they go through all the mystical mythological creatures? Not just the obscure ones that some of the psychics and miscellaneous are, either. A legendary griffin, chimera, etc. Go through as much mythology as possible. Group them according to either myths or general body type.
Anyone interested in seeing legendary myths?
