I've taken a liking to the universal combo miso posted somewhere deep deep in this thread.

the fact that its universal helps, but some chars require the j.B be delayed in order to land the entire combo, and after 214D, you can either 6C into oki, use 632146C special for 4.9k dmg total, set up steins, charge an SoD to eat primers, j.2C into oki, or even attempt to do an airgrab if they don't expect it.
