Card-specific notes from database

• (Konami neuron) Can be activated while "Macro Cosmos" or "Dimension Attractor" is applying, because the cost is to "discard this card" (not specifically "discard to the GY").
• (Konami neuron) Can be chained to an effect that includes Special Summoning a monster from the GY or banishing a card from the GY, even if there are no valid targets in the GY at the time of activation.
• (YGOResources) If an effect negates a monster effect activation and banishes that monster, you can chain "Ghost Belle & Haunted Mansion" if the negated effect was activated in the GY. You cannot chain it if the negated effect was activated outside the GY (hand, field, etc.).
• (YGOResources) Can be chained to an effect that Special Summons itself from the hand or GY (e.g., "Machina Fortress") if it was activated in the GY (such as by discarding itself). It cannot be chained if that same effect is activated in the hand by discarding other cards.
• (YGOResources) Cannot be chained to an effect that applies the Ritual Summoning effect of a Ritual Spell Card, because the effect itself does not specify Special Summoning from the GY.
• (YGOResources) Can be chained to the effect of "Doomking Balerdroch", even if the opponent has already applied its effect to banish a card from the GY that turn.
• (Konami neuron) If the activation of a Continuous Trap (e.g., "True Light") is negated by "Ghost Belle & Haunted Mansion", it is sent to the GY, but its effect that triggers when sent from the Spell & Trap Zone to the GY does not activate.
• (Konami neuron) If you draw "Ghost Belle & Haunted Mansion" immediately after a cost is paid (e.g., via "Squeeze of the Laze Moon" when a card is returned to the hand for the cost of "Blackwing - Zephyros the Elite"), you can chain the drawn "Ghost Belle & Haunted Mansion" to that activation.
