Forum:Blast with Chains vs Emergency Provisions

Player A activates "Dark Hole" to destroy opponent's monster equipped with "Blast with Chain". Player B then activates the effect of "Blast with Chain" to destroy face-down Spell/Trap card. Player A then chains "Emergency Provisions" to send two face-down cards to the graveyard, including the one targeted by the opponent.

Player B thinks that the effect of "Blast with Chain" would resolve first, thus destroying the face-down card before it is sent to the graveyard by "Emergency Provisions".

However, Player A thinks that both will be send to the graveyard for 2000 extra LP.

who is right?
