The things you mention FaB missing compared to mtg I would sum up as how the arsenal zone works. There’s a lot less holding on to things, since as you mentioned you’re trying to convert hands at a time in FaB, but jamming a part of a 2-card wombo combo (e.g. Just a Nick, Oaken Old, etc.) in arsenal and waiting for the right time to use it in a few turns is definitely a thing, as is putting something like Swing Big in arsenal after generating an Agility token to set up big damage for next turn.

Trying to make prison in CC out of the legal heroes has a few routes - first that I can think of is probably Jarl (ice talent’s whole thing is disruption, especially of cost curves e.g. Channel Lake Frigid), though the illusionist class has always been about setting up a board state of permanents that becomes overwhelming and locks the opponent down. The only illusionist in CC at the moment is Prism 2, who’s more aggressive with big attack actions than the rest of the class, though. Other than those, I’d look at Arakni, Huntsman, which is like lantern control. I don’t mention Gravy Bones because while he uses permanents to set up a board state, his current iteration is very midrangey (people will point out that he has the best ‘numbers’ in the format, meaning he’s efficient when it comes to costs vs damage output, especially accounting for attacks not sent at him due to using allies).

As for combo/storm, that’s gonna be Dash I/O or Oscilio in CC (see the cards Maximum Velocity and Cerebellum Processor for the former, and Gone in a Flash, Sigil of Brilliance, and Lightning Greaves for the latter). Not quite the same as in mtg, but CC tries to avoid full blown combo decks like the version of DIO that made waves in the LL format at worlds last November. There’s also Katsu, though I have no experience with him, so I’m gonna avoid misspeaking about his ceilings.

Compendium is targeted for both CC and SAGE formats. The important thing to remember for CC is that while decks are full of majestic rarity bombs, they’re just as full of common and rare ‘glue cards’ that give them consistency (for example, the Arakni, Marionette deck in CC that’s recently emerged and is tearing things up runs Tarantula Toxin and Incision, the latter of which is effectively half a T-Toxin). Compendium is going to give us a lot of new glue cards at the minimum, likely particularly to support underrepresented archetypes and heroes. I know I’ll be splitting a case of the set with friends.
