are you talking about Firana's opener? (Well, i've modify it a little bit to fit my Skill Speed, but here it is more or less...

Before you guys tell me that'm doing it wrong or doubling up on oGCD... ATM, i'm at 490 Skill speed, and i could not get the Duality Aeolian Edge inside the trick attack (500+ then it's possible for me at least), it always fell off a second or half a second before my AE lands. So i moved jugulate outside of the trick attack and right after dancing edge is applied.
also, i doubled trick attack and kassatsu oGCD because people done studies ad it showes if you apply Shadow Fang immediately after TA, your Shadow Fang will not get buffed by TA. So the animation lock from Kassatsu is my little buffer safety zone to register my Trick Attack.
Edit: You will need to either refresh Huton or your precast your Huton 15 seconds earlier before the tank pull... Either ways we ninja need 15-20 seconds before we can start our opener
