Shisui = Support Ninja, very good synergy with the current meta teams, and a nice team with Madara. He is a solid support ninja that buffs and removes.

Deidara = Pair him well and he can be deadly in every event we have, 1vs1 as well. you can go full buff with him with Edo Sasori and start throwing flames.

Kisame Samehada = I am not a big fan of him, but he is super useful, especially in Bonds , and space time for specific fights against certain teams. He can be a counter for a lot of teams, and if you have the initiative its gonna be bad for the opponent. really good ninja to have.

for my state i went for Deidara first and then grabbed Shisui. Kisame is still missing.. :P

Its up to you to decide who to catch depends the ninjas you have and the ninjas you will have in the future. ! good luck !
