Phase 0

[Viperlocc]

Rules say For a faster game, you can add a “phase 0” called Listen
At The Door. At the start of your turn, draw a face-down
Door card, which you may play or not. Then arrange cards
and Kick Open The Door normally. If you Loot The
Room, draw a face-down Treasure, not a Door.

Was alittle confused by this so want to know on the facedown you pick up can you only play it if its a curse or if it is a monster can you fight it?

Also if you fight the monster do you still kick open the door after that?

Also what does it mean by then arrange the cards? Is it talking about the cards you have in your hand and the one you picked up?

Are the rules the same for an epic game or are they changed some?
