Nice idea, these could be helpful.
That said, this looks more like an expedition video than a newbie guide video to me. You two are commonly making plays and taking them back before you end the turn without going over what risks you are weighing(which I admit, would be kinda hard to do in a shared call while in a match without giving anything away to your opponent). You end up referencing a bunch of cards, and a newbie might not know what card you two art talking about.
I'd think a guide would be more focused on how to play a specific faction, and what to think about as you play against other factions. Like, you'd just focus on you two playing just one deck and playing around the strategies of 2 or 3 other decks that you come across in normals. Or maybe just set up the matches with someone who has the decks you want to showcase yours against. Then you can freely share your thoughts on the match, which I feel would be more informative to newbies. Also, I'd try to limit the overload on new concepts by trying not to mention as many cards that aren't directly relevant to the game at hand. When you do talk about a card that's not on the field or in your hand at the time, you could also splice it into the video later in a special box or beside a pulsing arrow or something so everyone can see what card you are referencing.
If you wanted to go further, you could show some changes you can make with the deck(using commons and uncommons) between matches to show how you could evolve the deck to be stronger in the matchup. Explain some of how what you took out makes you weaker vs other things. In the end, possibly show off some different command zones within the same purity and strategy and talk a little bit about how you might change the deck to adapt to the new command zone to help other newbies modify their own decks.
Alternatively, if you want to keep them as expedition matches between factions, I'd try to keep playing your opponent until each side wins a match, then upload both, commenting on the difficulty of the matchup as appropriate. Seems more clean to me, but I'm weird.
Anyway. My two cents. Good luck.
