These 14-card packs each contain at least 1 traditional foil card, with the possibility of up to four cards of rare quality or better
But there are a whole ton of other benefits to playing them as well
Getting to self-wheel on EtB before flipping into a 9/9 that can fight something and generate you a decent chunk of mana, before flipping back to a self-wheel
While all Rare and Epic cards are foil, Common and Uncommon cards can also appear as foils through the dedicated foil slot in booster packs
There's also a Treasures subtheme because Ganax is so good at pooping them out: Magda, Brazen Outlaw and Magda, the Hoardmaster are both obvious inclusions and also support dragons specifically, but we can also tap our treasures to draw with Shimmer Dragon, turn them into repeatable mana rocks with Inspiring Statuary, flip Dowsing Device for super ramp + haste, use them to cascade with Rain of Riches, and goad creatures with Gloin, Dwarf Emissary
If so, I think itll be Once Upon a Time that gets the axe
