The team I have been using
Wave 1) STELLAAAAAAAAAAAAAAAAAAAAAAAH!!
Wave 2)Tactician's Commad and Tactician's Advice (Waver)+ Animal Communication and Long Distance Dash (Kintoki) --> GOLDEN DRIIIIIIVE!
Good night
Wave 3) Discerning Eye on Mordred (Waver) + Secret of Pedigree and Mana Burst (Mordred) + plug in Shakespeare and pop Enchant A + attack buff from plugsuit --> CLARENT BLOOD ARTHUR! --> some facecards to kill potential stragglers (usually Caesar with a bit of health)
Bryn is just there for the ride.
The team gets better if I swap Kintoki for my Carmilla because of class advantage and torture tecnique, but I can already consistently clear in 3 turns unless I forget something, oh and 34 boxes and no damn CE, this event hates me.
