Okay, so I got in a bit of play with the group... and holy crap, are they deadly.
Colette vs Lilith ended really badly for Lilith.
I linked a Mannequin to Cassandra and a Coryphee, and generated two Soulstones with Collette (using Reactivate and Manipulate Soulstone) turn 1. The team advanced, one Corphyee to each side of the field. Cassandra rushed forward towing her mannequin, since the enemy didn't have shooting, and since she's immune to melee for two turns.
Turn two opened with a Mannequin generating the no-weak damage aura, and then Cassandra using her southern charm to go and gank a few terror tot Nephs and get into melee with Lilith. She hits Lilith (using a Soulstone to do so), doing some damage. The trigger went off, and she got a breathe fire off that tags Lilith for 3, who cancelled it with a soulstone to heal. The corphyees and rest of the gang advance, and Colette generates a soulstone and makes a mechanical dove, which flew up into position. Charm protects Cassandra against every single one of Lilith's attacks (even if Lilith drew a 13, I was ready to soulstone to dodge it).
Next turn, Cassandra hits Lilith again and burns another terror tot. A corphyee gets charged by Teddy and Baby Kade, but makes it out due to the plus flips and cheats. A Showgirl runs up to support Cassandra. The Mature charges the Showgirl, but fails to kill her. A Corphyee moves up and does some decent damage to the Mature. The Mechanical Dove goes and hits Lilith with a Magician's duel (eat that, CA5->3 Lilith). Teddy kills one Corphyee. Lilith misses Cassandra repeatedly due to Southern Charm.
Last turn, I have cassandra nail Lilith AGAIN once, then used most of the misc. stuff. Collette gains reactivate, beams to swap places with the 1 HP Showgirl in melee with the mature, nails the Mature once with a Magician's duel. Next, she reactivates, generates a swan, hits the mature again and beams to swap places with the other Corphyee. The swan hits the Mature, immediately killing it. The Corphyee and Cassandra then gang up and beat the snot out of Lilith.
She's absolutely deadly, and that kind of mobility (and defense power) of her crew incredible.
