The first couple hundred packs you open from a set have a lot more value than the next couple hundred since the early packs are helping to fill out your collection with the lower-rarity cards in the set, while the later packs are just dead weight until you happen to hit a mythic naturally, hit a mythic wildcard, or fill the wildcard wheel
Kaust, Eyes of the Glade and Yarus, Roar of the Gods can both thrive with a creature like Aschloud Phoenix, as both of them can draw you cards with face-down creatures and turn creatures face up for free
Creatures (4) Planeswalkers (6) Lands (29) Spells (21) This brings us to number seven on our list: 7
On top of that, you included an Atraxa as an extra card and I actually already run an Atraxa deck
