Yes, Meta Knight is my favorite one, with lately becoming fan of the Armor Knight spirits since they're kinda Cool. (Black Knight + Halberd) So I've managed to complete the full setup, marking AK spirits on the box which were inherited into my Meta Knight. (I find it cool having printed spirits on the box your Amiibo is currently using.

(Black Knight sp sticker on the front of the box, Halberd on the back.)
