Collectible Card Game Headquarters

Is it possible to play either online or against the IA with 40 cards decks? io would love to do so since my friends and I use to draft my cube at cubetutor and we will love to use this decks to play it online via forge.

Thanks in advance!

In the preferences there's a checkbox that says "Deck Conformance". Not sure how that works when it comes to Online Multiplayer. I'd imagine it would inherit the preferences of the host.
