I know everyone's tight on money, myself included, trust me, I was unemployed even before the pandemic, but amiibos were very worth investing in for this game to me considering they never leave unless you tell them too.
I've added some extra Data in my main post with a table of all the duplicate encounters, if anybody is interested.
It has saved me so much time trying to acquire "dreamies" it's not even funny. I do NOT have the patience for that island bs. I did reset 3 days for dom as a starter, and even that had me grinding my teeth. I got raymond by chance, and he wasn't even someone I wanted. then today, in my campsite, stitches. Now he moved in in place of chester. It really is dumb luck.
I understand if it's a new villager the amiibo cards aren't out yet, so raymond or audie or someone is much harder to achieve, but I do think the amiibos will be released sooner or later. Or you can save all those nook miles you wasted and just trade for whoever you're looking for eventually.
