You're probably wondering why I've put deployments and activations as an advantage to JJ. This is something I probably should have done in my previous right up, but I wasn't quite confident in my assessment. Not to plug myself, but as I pointed out in my Raddus article for FFG, he kind of up ends the normal activation and deployment mechanics. When I wrote the article, it was based on the limited time we get with the cards in testing, and my own theories. Now that I've seen it in the wild in the hands of better players than myself, I'm standing by my analysis; Raddus equates to winning the deployment game and winning the activation game when it matters most.
JJ will be able to drop both Profundity and his Russian Doll Hammerhead at his will in a place and time that is most advantageous to himself. That's the core of why deployment and activations are important. Expect JJ to be far more aggressive in this game, probably going for the knock out punch as fast as possible. He is certain to take first player and unload the Profundity Russian Doll trick in full force (meaning the Hammerhead drops out of Profundity on the same turn Profundity comes on via Raddus and the Hammerhead takes the first activation since it's not limited by Raddus' restriction).
Broba's has to keep his Demo and Quasar well separated so that Profundity can hit them both in quick succession. He also has to do that while avoiding Admonition. That's a tall order. His only hope is in his squadron wing. That's a big advantage in his corner though. He can spread out his flotillas and milk Relay for all he can. Even if Demo and the Quasar get knocked out, he can still command 6 squadrons a turn from across the board. He has to quickly eliminate JJ's much smaller squadron force and go to work on Profundity when it jumps in.
I said last round that I'm not in the habit of picking against JJ unless it's a particularly bad matchup. This could be a challenging one with Broba's squadrons, but the hammer strike of Profundity I think is going to be too much to handle.
