Tentacle is probably her best physical attack. Samidare Slash/Hyper Fang Crush (latter is the same with higher lots-of-hits rate) are alright too. I like using Death Zapper since it also does good damage plus instant death. Using physicals with her final two Eye weapons are great because they do Charm/Control, even if the skill you're using already inflicts something. Time Stop, Enervation, Petro Breath, Death Breath, and Mind Blaster are all nice for status effects. Her innate Patk debuff skill comes in handy sometimes too (Enveration doesn't hit well on some bosses that her Patk debuff does)
Most of her skills aren't good for actual big damage (Tentacle is pretty nice though), but some notable ones are Mad Thunder (Before patchouli's buff, Mad Thunder is -the strongest elec attack in the game-), Dark Giga Flare, Comet, Cosmic Liner, Medoroa, and Punish the Judgment.
Poison Arts is good before like, stage 13.
All of Satori's support moves are good. Reflect Wall, Shield Wall, Area Heal, Refresh, Starlight Barrier, Leaf Shield (protects from 2 moves instead of one), Kabuff+1 (-does- stand up to Sanae's def buff, actually)
She's got good synergy with Reisen's special slayer in expansion. Meteor/Medoroa might be good for wiping yukkuris, since it shouldn't have reduced damage (Void element magic that ignores mdef), but I haven't tried. Bio is void element I think too, and should be more mp efficient, but I have -no- idea how strong it is.
