At the moment my Blood Angels army consists of the following..
Astorath the Grim in a 10 man Assault Squad with 2 Meltaguns, Sgt. Power Sword and a Sanguinary Priest with Jump Pack and Power Sword.
5 man Assault Terminator Squad - 3 Thunder Hammers, 2 Lightning Claws.
Baal Predator - Flamestorm…
2 scouting or outflanking Baal preds can change a game and can get inside an opponents head, so I’d definitely suggest another Baal.
As for the other one, I’d suggest a drop pod for getting the drag cannon furioso in early and wiping out a squad in cover or dropping the tactical squad on an objective. If you want more mobile armor to give your opponent fits, I’d suggest the razorback kit as it only two dollars more than the rhino and it comes with so much more. Magnets work wonders with that kit.
