I enjoyed the videos a lot. But I think it's not a benefit to have to click on a new video every 2-5 minutes. I also think explaining cards in groups will automatically employ you to talk about combinations/combo's/synergy. Although you do that pretty well already!
Another reason is that you see an introduction/outroduction after every card.
After a while I hear the sentences "I'm Coshade, I'm puddinghead" without the audio.
But again, I'm nitpicking here!
