i understand you trannies are too stupid to understand how alchemy packs actually work so i'll illuminate your dark peanuts for a brain

alchemy packs give you alchemy rares and mythics along rares and mythics from its parent set so when you complete the alchemy set you only get rare and mythic cards from the parent set, or wildcards. which means you'll completely both sets and also since alchemy only has uncommon rarity and up you'll also fill your vault much quicker than draftranning
