Witches' Quarrel: Small Beginnings

From BoardGameGeek:

Witches' Quarrel is a 2 player, 10-minute deckbuilder with legacy mechanics, where you play the role of a witch in a quarrel with another witch. Play spells to gain power, learn new spells, and deal or block damage. The first witch to take 10 damage loses. Play each game with a selection of 5 changing spells, but all the spells start in sealed envelopes: complete achievements to unlock each spell. Also unlock new witch characters and new starting spell options for each witch. Find a new snippet of lore about the child prodigies Yi-Feng and Nitya and the magical world they live in with each envelope. —description from the publisher
