.dck to .dec

[Haytrid]

So I searched for this and didn't come up with any hits so I apologize if this has been asked. My goo-fu is absolutely terrible.

My buddy and I draft sealed decks and well. . . every program I have used for filtering and doing quick searches of my opened packs are all so terrible. . .except Forge.

So what is the best way to get a .dck out of Forge and into a .dec, or .mwdeck format? I messed around with copying/pasting in the text files but it just doesn't work out in the end. I end up getting the cards imported but it doesn't preserve the deck/sideboard which was the original goal.

Thank you!
