It's worth pointing out that the Hyperspace Raddus Bomb is really more of a thought exercise than a likely result because which first player is going to be insane enough to look at a 3 ship Raddus fleet and pick Hyperspace Assault?
It's also worth mentioning that the Russian Radus+Profundity Doll bomb can be prevented simply by placing TIE's/X-Wings in close escort since the cards both specifically state that you can't deploy onto fighters.
So, my gut is, even if you can Raddus+Profundity two ships out of one in a daisy chain, clever Squadron positioning is going to make this extremely difficult to get that magic position. Especially since you opponent is going to get AT LEAST one activation to move the ambushed ship out of the trap after blasting the **** out of whoever. Sure you could block with a ship in the front, but if this is an ISD you're trying this on he's going to just LOVE that.
I will say you should still take Hyperspace Assault as one of your Objectives because it effectively means you are only bringing 2 Objective cards.
