You don't need swiftcast at all for RDM, just simply cure yourself pre pull. Then i would do something like vercure > acceleration > diversion > veraero/verthunder > fleche > contre sixte (i can fit both without clipping) verfire/verstone > veraero/verthunder > corp-a-corps > displacement > then fill manas to 40/40 (with one more) > manafication > corps-a-corps > melee combo > displacement > embolden > verholy/verflare. This allows you to get maximum damage from corps-a-corps/displacement from manafication. I'm sure someone much more hardcore than me will get a better opener, but this is what i have come up with thus far
