Features hard knockdown combos on several characters.
After a hard knockdown with 2C, you can set up oki depending on your Arcana choice. E.g. with the Love Arcana, you can do:
2C (short delay) 5[E] 236E
2C (delay) 8B j.236E
to set up oki with a Love ball. (Note that only Love can cancel specials into Arcana specials while in EF.)
