Majo x Majo

User summary

A Japanese 2-player combat card game. Each player chooses two of nine witches, that all have their unique combination of spells, and take turns drawing cards from a deck consisting of 6 types of mana. Players build up their mana pools by playing "towers" (stacks) of cards from their hands, and can then activate these towers to unleash the spells of one or both of their witches.
Damage is represented by drawing cards from the mana deck; if two identical cards are drawn the pair dies.

Translated box blurb
When the stars align in the sky,
the witches prepare
for a battle of life and death
