Previous Versions can be found here.Force of Nature is a Kindness deck specific effect card. It increases the maximum HP of a monster by 3 as well as heal it for 3 HP. Good on monsters with Taunt. Also very effective on Papyrus to keep him alive so he can clear out the entire board.
Force of Nature also houses a sort of offensive pressure. Using it to buff up a monster's HP, then using Madjick or Disco Ball to swap it for a higher ATK is a common strategy with monsters like Papyrus, who can perform a 1 turn kill by using many HP buffing spells and the aforementioned Madjick and Disco Ball to deal 30 damage to the enemy player.
