Card Rules: Rulings powered by The Netrep API. Cards that are Tributed or Discarded are included, because they are also 'sent to the Graveyard'. The effects of multiple 'Skull Invitation' are cumulative. If 'Dark Hole' destroys monsters controlled by both players, the damage from 'Skull Invitation' is applied to both players simultaneously. If you draw the final piece of 'Exodia' with 'Graceful Charity' and have all 5 pieces of 'Exodia' in your hand after discarding, you win the Duel even if the damage resulting from 'Skull Invitation' would reduce your Life Points to 0. [Re: Amplifier] If you have 'Jinzo with Amplifier', your Trap Cards are not negated and their effects are applied, including 'Aqua Chorus', 'Royal Command', 'Royal Oppression', 'Coffin Seller', 'Forced Requisition', 'Mirror Wall', 'Gravity Bind', 'Rivalry of Warlords', 'Minor Goblin Official', 'Final Attack Orders', 'Pitch Black Power Stone', 'Bad Reaction to Simochi', 'Skull Invitation', 'Skull Lair', 'The Eye of Truth', 'Spirit Invitation', 'Respect Play', 'Ring of Destruction', 'Metalmorph', 'Torrential Tribute', 'Self-Destruct Button', 'Zero Gravity', and 'Big Burn'. [Re: Exchange of the Spirit] 'Exchange of the Spirit' does not 'send' cards to the Graveyard it swaps the cards in your Deck with those in your Graveyard. So the effects of cards like 'Penguin Knight', 'Cockroach Knight', or 'Archfiend of Gilfer' will not activate, nor would the effect of 'Skull Invitation' deal any damage. If 'Banisher of Light' is on the field no cards will become removed from play because they are not being sent to the Graveyard. [Re: Graceful Charity] If 'Solemn Wishes' is on the field when you activate 'Graceful Charity', you gain 500 Life Points after you finish both drawing and discarding.If 'Solemn Wishes' and 'Skull Invitation' are on the field, you finish both drawing and discarding for the effect of 'Graceful Charity' then you gain 500 Life Points, then you lose 600 Life Points.
