"Drytron Delta Altais":

OCG Rulings

The text that states this card cannot be Normal Summoned/Set and must be Special Summoned by a "Drytron" card's effect is not an effect.^[1]
Even if it was Special Summoned by the effect of a "Drytron" card and then sent to the GY, it cannot be Special Summoned by a non-"Drytron" card effect.^[1]
This card's effect that Special Summons it is an Ignition Effect that activates in the hand or GY. (This effect does not target. Tributing another "Drytron" monster or a Ritual Monster is the cost to activate this effect.)^[1]
After Special Summoning this card in Defense Position, you can then apply the part of the effect that reveals a Ritual Monster/Spell and draws a card.^[1]

Q: Can the effect of "Ghost Belle & Haunted Mansion" be activated in response to the effect of "Drytron Alpha Thuban"?

A: When the effect of "Drytron Alpha Thuban" is activated in the hand, it is treated as an effect that Special Summons a monster from the hand, not an effect that Special Summons a monster from the GY. Therefore, the effect of "Ghost Belle & Haunted Mansion" cannot be activated in response to the effect of "Drytron Alpha Thuban" activated in the hand.
When the effect of "Drytron Alpha Thuban" is activated in the GY, it is treated as an effect that Special Summons a monster from the GY, not an effect that Special Summons a monster from the hand.
