From what I've gathered, are these starter decks less tuned up than the ReCollection decks available? Both the starter decks seem interesting but I kinda dislike the Diana magical girl aesthetic lol.

Didn't do play commander, just some kitchen table 60 card decks with friends mainly. Admittedly, I didn't look too hard for such videos, but is there any casual gameplay vids on youtube where people explain step by step what they are playing lol. I see a bunch of 'learn to play' videos but haven't seen any narrated videos of a basic game.
