If Coelacanth negates Fishborg Blaster's effect, can it still be used as Synchro Material for a non-WATER Synchro?!
Coelacanth Special Summons Fishborg Blaster with its effects negated.
No. Fishborg Blaster's restriction on Synchro Materials is a condition, not an activated effect, so it still applies even if its effects are negated.
Which Necrovalley errata is used in Edison and what does it negate?!
Discussion about Necrovalley's Edison-era text.
Edison uses era-appropriate Necrovalley text (as on the site's errata page). It does not negate some effects like Rekindling/Treeborn/Fishborg in that version, but still blocks many GY interactions.

Discarding 1 card is a cost to activate the effect.
The requirement that you use WATER-Attribute Synchro Material Monsters when using this monster for a Synchro Summon is a condition, not an effect. It cannot be negated by “Skill Drain.”
