LightMonster

Any effect that would inflict damage to a player increases their Life Points by the same amount, instead. During either player's turn, when a Spell, Trap, Spell/Trap effect, or Effect Monster's effect is activated that would destroy a monster(s) on the field: You can send 1 card from your hand to the Graveyard; negate the activation and destroy it.
