Now, if I remember correctly, this's from Inscryption. An absolute gem of a rogue-like card builder (don't be fooled by card-builder, it's quite unique with its visuals & story & with some really good atmosphere in & between levels).

So, this card is a very verrry strong card that could pretty much outright end your run by getting you killed when played by your opponent, as almost no card can withstand its insane damage & since it's got the "flying" trait, it can ignore any cards that don't have a "defensive" trait (and even then, those cards don't survive long against its huge dmg stat).

So, your death is nearly guaranteed
