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.
Beta 26.0 made this card replace Heal as a part of a new player's starting cardpool.
