Here's something I love to do with 6c while the opponent is cursed, and it refreshes the curse.
6c->d+a+b bug->c->-2c->jump up and->j.b->j.c->j.a
a, and b bugs are required for Tager for d-bug to work in a true combo, cause when you do the 6c->c->2c, the c bug hits Tager, giving a small amount of recovery time for Tager, making you loose your true combo.
That combo puts your enemy on top of the d bug, giving you lots of time to jump up there and finish the combo the j.b->j.c->j.a part of the combo.
It can also be done without the j.b->c->6c->d+a+b bug->c->-2c->jump up and->j.b->j.c->j.a, but it does less damage, I guess the higher the combo the less damage it does er something.
Another cursed combo
j.b->d bug->c bug->b plus an a bug->j.b->jump up and->j.b->j.c->j.a
^(c works to, if I'm using b, I usually use the trigger, cause then it sets off the a bug at the same time)
