Cr.C is an excellent poke, most Krausers will Cr.C, rdp+D alot because it's a good frametrap, combo's if the Cr.C hits, and it's really safe despite being some frames negative on block due to good pushback.
If you are going to hit confirm, Cr.B, Cr.B, Cr.A, dp+D does some decent damage. There's also Cr.B, Cr.A, ABC, Cr.C, f hcf+C in any mode with EXTRA gauge.
Kaiser wave is a great tool for keep away, since you can't really jump over it. His hcb f+p has start up invul like goro's dp+k. Qcf hcb+p makes for an alright aa, and if the DM version ends in the corner you can juggle the opponent with a Cl.D to reset them.
I'd say mostly remember his Cr.C rdp+D, that string gets abused to no end.
