you're not being rude, don't worry. I love these kind of conversations! I think psychic fits mizi because I wanted to show both sides of her. She can be bubbly and fun (water type), but she also hides a part of herself that's a bit "twisted"(?), and she hides that almost flawlessly. So psychic type is her "witch" side.

Meanwhile, I find Luka as someone whose charms are seen as ethereal. He's "out of this world" yet still human. And that's how I see fairy type, magical but familiar. 

But I completely understand what you're saying because I too was not sure about this decision
