Well first the event type is farm like Odettes (but luckily I won't have to spend SC, as Shiho isn't my Shaman of choice... and with lolis being added I will be able to get her... that being Kaguya.)
Shiho, Platinum Shaman and the Event unit.
Liddy/Riddy, Platinum Pegasus Knight and one of the spotlight units.
Roberto, Gold Healer and one of the spotlight units. Also boost Alcohol drops.
Silver Drops for the event.
