First I'd like to say hi there!, I'm posting a few of the deck the halls cards in assistance to @hikaymm so follow my posts here to make sure you don't miss any of the days! NEXT Let's get to the AMV's, I can't say they are my favorite as I have now only watched over a handful but here are a couple that I enjoyed while searching!
This one I like the song and the clips went almost hand in had with it and I also liked the 3D rendered character who is seemingly singing the song haha Video by AwesomeDarkness on YouTube
This one has the same toradora scene as the last and I realllyyyyy need to watch that show but this song is just classic Christmas song how couldn't it be on this card? Video by GrayFullbusterLockser on YouTube
Aaaaand lastly this one, another with a seemingly singing hat acted added in and I like that, also if you didn't notice MORE TORADORA God I need to watch the that show...
