Longevity is a Kindness Deck specific Effect Card. It used to double the HP of a selected monster, both ally and enemy, for 6G. This was decreased to 5G in Alpha 3.2 and further decreased to 3G in Beta 2.0.
However, while it would double the current and maximum HP of the selected monster, its calculations go by the current HP of that monster, not its maximum. (So if this card was used on a monster with, say, 10 max HP, but 2 current HP, it would only heal and raise the monster by 2 HP.) And because the monster's HP increases by the same ammount as it gets healed, damaged monsters would still be damaged. Because of this, they stay vulnerable to cards like Asgore.
Beta 7.4 changed it by fully healing the monster, and then give the HP bonus. But this bonus is only 75% instead of 100%. This made it the same as Bravery's Aaron's Secret again (at that time), which was nerfed to a 75% ATK bonus some time earlier. Beta 16.0 increased its cost to 5G. And Beta 17.0 made it an Epic, swapping its Rarity with that of Soothing.
