Just to clarify:
Can Number S39 Utopia the Lightning get negated by Herald of the Arc Light
Only if you control both monsters. Arc Light's effect to negate activates, and S39 prevents the opponent from activating effects once it declares an attack.
Can Evilswarm Castor get negated by Herald of the Arc Light
No, because Castor does not activate, and Arc Light can only negate the activation of cards or effects.
Can I negate Herald of the Arc Light with Forbidden Chalice and Heralds effect is negated even though it has tributed for cost?
This question is somewhat unclear, so here are 3 scenarios:
Hope that answers your questions.
