I don't know if anyone's posted this yet but if you use Mystic box with Horus lv 6 it destroys the other monster but doesn't switch control of Horus to your opponent
Tried it and it didn't work form some reason you can't select him, so far as I know it only works on level 6 and I'm pretty sure it doesn't work on level 8 because it's not immune to spell cards it can just destroy them
