Cleric Resurrection - What card to discard?

[lizzy]

Hello,
I promise I have searched the forums (perhaps inadequately) and have found many posts concerning clerical resurrection, but none quite answering my question:
When a cleric resurrects a card, does the card discarded need to match the pile the player is drawing from? For example, when resurrecting a card from the discarded door pile to break down the door, does the card the player discards need to be a door card, or can it be a treasure card?

TIA for your help :)
