Old Hollywood Grid and Casting Call together means the runner has to run a server twice and take four tags to steal the agenda (they get the tags on the first run even though they can't steal the agenda yet). This is unsafe because of Consulting Visit finding Boom.
You can use Dedication Ceremony on the turn you use Casting Call to help you score 3 point agendas or a bigger Beale. If the runner decides to wait until after you've scored the agenda to trash OHG, then you can even use Dedication on the next turn to save some credits and score the agenda the turn after since it is as safe as it was before.
Use Data Raven or Thoth on servers to ensure that the runner can't steal Quantum Predictive Model. You can score it without any tricks, to help you get to seven points easier. Use Preemptive Action or Hades Fragment to recycle your combo pieces if necessary.
