You can use the Sukanahime if it's スクナヒメ[プレミアム], then she got a upgrade and gain chase damage in the new episode
Kohri as a 12* is not very useful, only 140/150% E type, and a additional 25% H type if you use ice element weapon
Koiho is 50/60% e-type damage and each addtitional fire chip gives another 15%
Getten is a element boost chip, so if you activate it, it gives you 90/100 Dark element boost, not useful.
You should do the ex stage to get all the medal, and see what the ability of the Anette chip is, these event chip are suually strong.
Lutyrus isn't very strong, 90/100% E-type damage, and even at max level, her activation rate is small++, and even if activated, she only last 15 second, the only really useful chip in those exahcange would be avenger.
Optrelieto - 100/110% E type damage, an aditional 50% if your HP is below 50%
Ideal Duo - 200/120% E-type, 10% more for each fire type
Avenger - Fire element + 50/60 and Chase damage of 110/120%, and if you fill ou thte friend bar, you get 35 second of activation.
So out of those, Avenger and Ideal are worth getting.
