greetings...i assume your searching for fire main formations...your ninjas collection is small and you still need to work on it surely..but its holding good ninjas that you can. use them to create great teams..as for the summon unfortunately there is no information..so i assume you have some of the purple summons and few of the orange quality summons.... i will be giving few examples and i hope you find those examples to be an aid for you....

first team example

a balanced team with a great harmony among the team members...on this formation your depending on your main to cause the damage...itachi is playing an important part here since you can. use him to counter your enemy barrier...while still having itachi barrier active it will arm your team with a deadly benefit that will allow you to trigger your main and sasori or kimimaro mystery at the same round...this will surely cause high damage to your enemy ..with such formation sasori puppet will have the highest chance to survive this will allow him to use the iron sand world order mystery instead of puppet summoning..problems for you here might be barrier changers ninjas and control ninjas....

most of the talents is giving benefits for your main and damage boosting ....with the summon you will be able to create a deadly chain of chase attacks holding harsh debuffs indeed..

............................

second team example

a formation with a wonderful team working that can. allow you to counter most of the hard situation...your formation is depending on your main also...having anko on your formation to create a barrier which will allow her to boost herself and your main....sakura will be serving as a healing support and this will allow you to survive dangerous debuffs and live for a while longer....kankuro will be a threat to your enemy since he will be generating chakra with his chase attack..reaching the second round and using your main mystery will cause a high damage with a chain of chase attacks that will allow your team to gain chakra in order to trigger nearly all your formation ninjas mystery at the same round...this will bring your enemy into a dreadful situation surely...problems for you here might be barrier changers and control ninjas also....

those talents will allow your formation to have a great balanced potential..the summon will aid on making the chase combo chain complete ...

................................

this was all of the examples. hope you find them worthy and helpful for you on the times of need..wish to you wonderful results and fruitful efforts !..

best of luck.....

Dear Dusk, thanks for your time and effort, really aprreciate the detailed intel.

Any suggestions, which recruits should I focus next?

your welcome !...in case you will be fire main for a long while then my suggestions would be to focus on recruiting shisui and iruka they can be working so well with scarlet blaze and midnight blade and they will be your very first special ninjas to carry you on your road to power...they can. also serve you for a long while and they can be great on most of the battlefield situation... they are recommended surely till you start on building your ninjas collection with more high quality ninjas..if your wiling to become wind or earth or water mains then focus on recruiting minato jonin...he can be wonderful specially with those 3 mains..also minato jonin can work well with scarlet blaze..maybe soon the sage treasure event might arrive at the hot topics event...this will be your chance to recruit iruka and by that you will be taking your first step to build your special team..best of luck..
