For reference, Japanese booser boxes contain ten packs of ten cards, not the 36 boosters you get from a typical Western booster box

Gods Willing and Growth Spiral are commons, Despark is an uncommon, and Approach of the Second Sun is a rare, but if you are opening a bunch of packs to try to complete a Strixhaven set, you'll still have to pay the full Mystical Archive price for these cards, even though they are unnecessary for gameplay because you likely already have (or could easily acquire) the lower-rarity version if you want to play them in your deck
