Attempting to play Archenemy

Got 3.0 installed seemingly correct. I can see all the cards and game types in the deck editor (Archenemy , EDH, Planechase)
But I created an Archenemy deck with the placeholder card in it, and launching a match with that deck (Or the preconstructed Archenemy decks) just starts a regular match with me at 40 health and the schemes resolving every round randomly versus a single opponent.
What am I missing? I've searched the forums but without any luck. The one hit I get describing how to play (other than include the placeholder in your deck) is for Forge and not Manalink 3.0.
Thanks in advance!
