More analysis on Wisp.
So you find the magic lamp randomly somewhere in your town. Dialogue will pop up telling to walk in a certain direction. Once you've walked around the area a bit, you'll find the lamp.
Wisp grants only 1 wish per day (but you can TT of course). When you scan a Villager card, for example, I scanned Muffy. You can receive a gift from her or ask her to move in. Without a vacancy, she can't move in unless you decide to move a Villager out. I wanted to move Timbra out, but her name didn't pop up at first, however you tap the "No! Ask someone else to move!" Option to cycle through your town villagers until you select the one to move out.
You can even select a Villager that already has a set date to move out. For example, Elmer was set to move out Jan. 3, and the day in my town is currently Dec. 27th. When I scanned my Diva card, I selected Elmer to move out the next day ahead of his scheduled time! When you go outside, Elmer is immediately placed in boxes. He is gone the following day and Muffy plotted her spot. Muffy'S house was up the following daY.
I haven't tried getting an item from a Villager amiibo yet, nor have I scanned a special amiibo either. Will check it out next.
