Hi Ragnarok,
I would suggest you go with Blue black shaman, Green colonel, and Green dragonman.

Why I selected these

Blue Shaman has stun ability you can use saya on it and put some speed. So basically enemy team won't able to do anything other than getting stunned. Now Green Dragonman work great with Blue Shaman as it will Boost speed so your Blue Shaman will get more chance to stun the enemy.
and Every team should have a healer partner and in your list, Green Colonel is the great healer.

War Pattern suggestion :
For Blue Shaman focus on Speed and Damage with Saya.
For Dragonman Focus on Fully Speed and Defence (4 cat + 2 Bull).
For Colonel Focus on More Hp and Defence.

Hope this will help you! 🙂

Thanks =)

I am curious about Saya on Blue-Black Shaman but am currently using cat there.

I think I forgot to mention that I have a Blue berserker as a healer as well. A partner I think many overlooks since its a 3 star to start with but few can compare to its mass healing. And my issue with green colonel is that she has 1 resurrect and one heal, on the other hand, she does allot more dmg then blue berserk.

Another issue I have with 5-star partners is that they are notoriously hard to skill level and Green dragon man , Blue berserker is ez

Another question I have is if you have found any combination of partners where you use whale pattern or a mix of whale pattern and hippo?

I am waiting to get Blue nomad to try out the endurance/hp style to its limits 

Lastly, any fun combinations that are rare that you want to share? (Partners patterns or synergies) I like to think outside of the box and would find it a fun challenge if we could come up with something new here.

Could you build a set up where you just keep the enemy stunned from start to end?

CAT combination also not bad for blue shaman but using saya on it gives you an extra 25% chance to give stun effect that means there is a chance to give stun buff on every hit.

About Berserker, it works well if your team All Team has good HP As its heal all team member. But Colonel works great if you work with high damage deal as its revive skill helps a lot. You can use Hippo and Bull on the colonel. but if you planned to use it with speed team then use cat and Left Hand Speed pattern.

Green Colonel always better than berserker when you awaken it to 3 stars (see below image). Each Stat is better. Even see Speed. She can be in your speed team.

Skill upgrade issue is there in 5-star partner but there is chance that you can get skill upgrade. 3-star partners are good at starting but after sometime, you will realize that I should have upgraded 5 start instead. But.. But.. there are good 3 star also like Green Dragonmen. Top 3 players in ranked match also use it sometime.

Blue Shaman (With Saya and Left-hand Speed), Green Dragonman (Full Speed Build with DEF) , Green Colonel, Last One partner take high Damage Partner As now you have the speed to why not to kill the enemy faster. You can use RED Double Blade Girl. It has High Damage also its 2nd ability Has sleep effect that is similar to stun. Here is your fully stun speed team. 

Thanks allot man =)

I can see your points and I am excited to try them out. Was funny you mentioned the Red double-bladed girl since I literally just spun her =0

The Nomads can you do without them in your opinion or are they just too good?
