Jackson has been ground up and distributed to each faction in unique ways.
Teki has heritage/hasty + shuffle effects (mutate for isntance), as well as draw filtering effects to mitigate bad draw.
Weyland has audacity, liquidation, and other trash cards effects mixed with preemptive (sure preemptive works with anyone, but weyland can stuff cards instead of having to survive a turn to simply discarding).
NBN, the faction whose apparant skill set, among many things, includes agenda manipulation, has varied effects like special report, claire, corp shuffle (this rotates?), Disposable HQ, DBS, Sensie, etc. Easy to handle here.
HB has few options, but could easily import these from other factions, since they have most things they need in house. Also HB is usually just scoring agendas rather than filtering them.
The loss of howard is much more overstated now than it was when realized he was leaving. In fact, its really his draw ability that we'll miss, not just the holding in archives to keep RnD strong.
