necrofear vs big burn

[1cup]

if this is a repeat question, then just ignore and i'll scour for it again

Dark Necrofear
Effect Monster (Fiend / DARK / 8 Stars / ATK 2200 / DEF 2800)

This card cannot be Normal Summoned or Set. This card can only be Special Summoned by removing from play 3 Fiend-Type monsters in your Graveyard.

i assume necrofear targets 3 cards in the grave, thusly if the turn player were to attempt to remove 3 fiends, but the opponent activates Big Burn...

Big Burn
Normal Trap

You can only activate this card when your opponent activates a card that targets a monster in the Graveyard. Remove from play all monsters in both players' Graveyards.
​

...necrofear would fail to summon, remain in the turn player's hand and both players rfg their respective graveyard monsters.

Dark Necrofear doesnt target anything in the graveyard. Removing the 3 Fiend-Type monsters is a cost to special summon it from your hand.

Here is the Official ruling.

You can only activate "Big Burn" when an EFFECT that removes monsters in the Graveyard is activated. So you can't activate "Big Burn" when a player removes monsters in the Graveyard as a COST to Special Summon "Black Luster Soldier - Envoy of the Beginning", "Chaos Emperor Dragon - Envoy of the End", or to activate the effect of "Strike Ninja" or "Freed the Brave Wanderer". Nor can you use "Big Burn" when monsters are removed for a condition.
