Card Rulings:D/D/D Rebel King Leonidas

Pendulum Effect

 * "When you take damage from a card effect (except during the Damage Step): You can destroy this card, and if you do, any effect that would inflict damage increases LP by the same amount instead for the rest of this turn." effect starts a Chain Link. (This effect cannot be activated during the Damage Step. Destroying this card is considered the last thing to happen when this effect resolves.)


 * If the "When you take damage from a card effect (except during the Damage Step): You can destroy this card, and if you do, any effect that would inflict damage increases LP by the same amount instead for the rest of this turn." effect is activated and "Mystical Space Typhoon" is activated in a chain, destroying "DDD Leonidas the Rebellious Lord", the effect is not applied. ("DDD Leonidas the Rebellious Lord" is not destroyed by its own effect and effects that would inflict damage are not changed to increase Life Points.)


 * After the "When you take damage from a card effect (except during the Damage Step): You can destroy this card, and if you do, any effect that would inflict damage increases LP by the same amount instead for the rest of this turn." effect resolves, any effect that would inflict damage increases LP by the same amount instead. Therefore, if an effect inflicts damage to you, you gain Life Points, and if an effect inflicts damage to the opponent, the opponent gain Life Points.


 * After the "When you take damage from a card effect (except during the Damage Step): You can destroy this card, and if you do, any effect that would inflict damage increases LP by the same amount instead for the rest of this turn." effect resolves, any effect that would inflict damage increases LP by the same amount instead. Therefore, if you take damage by the effect of "Gagaga Cowboy" and the Pendulum Effect of "DDD Leonidas the Rebellious Lord" is activated, that damage that was already taken is not changed to gain Life Points.


 * If you take effect damage while you control 2 copies of "DDD Leonidas the Rebellious Lord" in your Pendulum Zones, the "When you take damage from a card effect (except during the Damage Step): You can destroy this card, and if you do, any effect that would inflict damage increases LP by the same amount instead for the rest of this turn." effect of each copy of "DDD Leonidas the Rebellious Lord" can be activated in a chain. However, even if the "any effect that would inflict damage increases LP by the same amount instead for the rest of this turn." effect of both copies is applied, the effect damage is only changed to increase Life Points once. (The Life Points recovered is not doubled. This is no different from only applying the effect of 1 copy of "DDD Leonidas the Rebellious Lord".)

Monster Effect

 * "When you take damage from a card effect (except during the Damage Step): You can Special Summon this card from your hand, and if you do, gain LP equal to the damage you took." effect is a Trigger Effect. (This effect does not target. It cannot be activated during the Damage Step.)


 * "Special Summon this card from your hand" and "gain LP equal to the damage you took" are considered to happen simultaneously.


 * "Any effect damage you take becomes 0." effect is a Continuous Effect.


 * While you control "DDD Leonidas the Rebellious Lord", if "Ring of Destruction" targets a monster other than "DDD Leonidas the Rebellious Lord", since the "Any effect damage you take becomes 0." effec is applied, you take no effect damage and only the opponent takes damage. If "Ring of Destruction" targets "DDD Leonidas the Rebellious Lord", since the "Any effect damage you take becomes 0." effect is not applied, both players take damage.


 * While the effect of "Bad Reaction to Simochi" is being applied, if the "When you take damage from a card effect (except during the Damage Step): You can Special Summon this card from your hand, and if you do, gain LP equal to the damage you took." effect is activated, "DDD Leonidas the Rebellious Lord" will be Special Summoned normally. However, because the effect of "Bad Reaction to Simochi" is being applied, the "gain LP equal to the damage you took." effect will be changed to inflict damage, but since the "Any effect damage you take becomes 0." effect is also applied, you take no damage.


 * If the "When you take damage from a card effect (except during the Damage Step): You can Special Summon this card from your hand, and if you do, gain LP equal to the damage you took." effect is activated and "Vanity's Emptiness" is activated in a chain, the effect of "DDD Leonidas the Rebellious Lord" is not applied. "DDD Leonidas the Rebellious Lord" is not Special Summoned and remains in the hand. You don't gain Life Points.


 * When you would take effect damage while the effect of "Rainbow Life" is being applied, since you would gain Life Points instead, the "When you take damage from a card effect (except during the Damage Step): You can Special Summon this card from your hand, and if you do, gain LP equal to the damage you took." effect cannot be activated.


 * When you would take effect damage while the effect of "One Day of Peace" is being applied, since you would take 0 damage, the "When you take damage from a card effect (except during the Damage Step): You can Special Summon this card from your hand, and if you do, gain LP equal to the damage you took." effect cannot be activated.
