Forum:Number C32 Shark Drake Vice: Simultaneous cost?

Hi there. This question is about Number C32: Shark Drake Vice: This card has a double cost to use the effect of reducing a monster's atk to 0: It must detach a material AND banish a graveyard monster: Tell me: When i declare i'm activating the effect, should i choose both the material i want to detach AND the monster i wanna banish before sending the material to the graveyard, or i detach the material and THEN banish a monster from the graveyard, including the one i just detached?
