Forum:Deck Devi + Rabbit Q

So my friend and I were wondering about these three rulings.

Situation 1:

Player A has a face-up Tenki, face-up Vorse Raider, and a Deck Devastation Virus face-down.

Player B has a previously set Compulsatory Evacuation Device.

It is Player B's turn. During Player B's Standby phase, Player A activates Deck Devastation Virus.

Player B responds by activating their face-down Compulsatory Evacuation Device targetting Vorse Raider.

Is this play legitimate? Or does Deck Devastation Virus tribute Vorse Raider as a cost?

Situation 2:

When a player has any XYZ materials on a monster and they have a face-up macro cosmos, do their detached materials get Banished, or do they get sent to the grave?

Situation 3:

Player A has a face-down compulatory evacuation device.

Player B summons a rescue Rabbit.

Player A responds by activating his face-down.

Player B says that he can use Rescue Rabbit's effect because it isn't being negated.

Is player B right?
