Savage Mana allows you to put a target that Haka destroys under Savage Mana.
Prime Warden Captain Cosmic's base power allows you to shuffle a destroyed construct into your deck and then either draw or play a card.
If Haka destroys a construct, can it be shuffled into Captain Cosmic's deck and then placed under Savage Mana? Can it be placed under Savage Mana and then shuffled into Captain Cosmic's deck?
My intuition is that you have to choose one or the other of these, you don't get to do both, but I'm not 100% sure.
