Ours not to reason why...
I've been streaming (read: destroying) Persona 4 and just slogged through that fight, you can bet that was stuck in my head the whole time.
Trick for the Shadow Teddie fight:
Nihil Claw, or whatever it is, takes two turns to charge, and hits on the third turn. Have everyone guard on the second turn and keep guarding until the attack goes through. If a character is guarded during that attack, it's damage is cut down to a fraction of its total power.
You could also feasibly DPS during the two turn charge, but you'd have to have level three spells or a Persona with a high damage attack.
