If Goblin Zombie is used as Synchro material for Brionac, can you call priority?✓
Goblin Zombie triggers after being sent to the GY.
No. Goblin Zombie is mandatory and starts a chain, so you do not retain ignition priority.
If I Tribute Goblin Zombie for Caius, can I chain Blackwing - Chariot to Caius?!
Goblin Zombie is Tributed to Summon Caius and both effects activate.
Goblin Zombie is Chain Link 1 and Caius is Chain Link 2, so you can chain Blackwing - Chariot to Caius.

● Both of these effects are mandatory.
● If this card is used as Synchro Material for "Brionac, Dragon of the Ice Barrier",
this card's ② effect must trigger. Because of this, you don't retain Ignition Priority,
and can't activate Brionac's effect until Goblin Zombie has finished resolving.

(1) When this card inflicts Battle Damage to your opponent, send the top card of their Deck to the Graveyard. (2) When this card is sent from the field to the Graveyard, add 1 Zombie-Type monster with 1200 or less DEF from your Deck to your hand.
The (1) mandatory Trigger Effect activates in Substep 5 - After Damage Calculation of the Damage Step.
If "Macro Cosmos" applies, the top card of your opponent's Deck is removed from play instead.
The (2) mandatory Trigger Effect cannot miss the timing.
This effect only activates if this card is sent to the Graveyard, not if removed from play.
This effect activates even if you have no targets remaining in your Deck.
This effect will activate even during the Damage Step.
If used in a Synchro Summon, this effect must activate; you cannot claim Ignition Effect Priority to activate the Ignition Effect of the Synchro Monster (ex: “Brionac, Dragon of the Ice Barrier”).
If used to Synchro Summon “Mist Wurm”, both mandatory Trigger Effects activate: “Goblin Zombie” (Chain Link 1) activates first, then “Mist Wurm” (Chain Link 2) if the Synchro Summon is successful.
