When I start a feast match, I draw and then redraw if I don't get Bole/Ewer first. If I get either of those first, I spread them. Then I Royal Road the next card. This lets me either buff the defense of someone (add in Synastry) or give myself a nice MP regen. You can use a mixture of Noct and Diu. You are only locked to a particular stance when someone is still alive and has attacked/used a skill on you. I usually go Diu first and get the regen buffs on everyone and then Celestial Opposing them to be longer, along with the Aspected Benefic version of the regen, right before the gates open. Then I swap to Noct and put up shields and then we burn their ranged as fast as humanly possible.

Literally spamming Aspected Benefic will work wonders in almost all situations where if someone is only being chased by one person. If being chased by two, you need to have Synastry up on someone so you can get the healing potency up buff, to keep up with the damage using only Aspected Benefic. If you're being chased, you can use Lightspeed, Swiftcast, and Surecast on Blizzard 2 (cross classed from BLM) to keep them binded in place from chasing you, giving you a small window to breath and catch up.
