Rulings
- Spell Canceller's effect is similar to Imperial Order.
- If Last Will's effect is applying (its 'state' is in effect) and Spell Canceller is Summoned, Spell Canceller will not negate the effect of Last Will.
- You can Special Summon Spell Canceller with Premature Burial; the effect of Premature Burial is negated by Spell Canceller so if Premature Burial is destroyed, Spell Canceller is not destroyed and remains on the field.
- You can chain Call of the Haunted to a Spell Card, and Special Summon Spell Canceller, to negate the effect of the Spell Card.
- You can activate Spiritualism when Spell Canceller is face-up on the field because its activation and effect cannot be negated.
- When Spell Canceller is face-up on the field, you can activate the GY effect of Dark Necrofear (because it is a monster effect) and equip it to a monster, but the effect of Dark Necrofear after it is equipped will be negated because it is then an Equip Spell Card.

- Q: Can "Spell Canceller" negate the activation of "Spiritualism"? A: "Imperial Order" and "Spell Canceller" cannot negate the activation or effect of "Spiritualism."
