Hey guys!

A very good breakthrough

Mystery: Both + and Y are decent upgrades, increasing the enemy units hit

I'd generally prefer using Y though since it can work with many more teams as it reduces your chakra cost to 40

+ is only useful when you are versus super armor ninjas

Standard Attack: There is only +1 and +2 in here, the change in +1 is having a 100% ignite chance, while the change in +2 is hitting entire enemy team (9 units max in a single team) so it can be very useful if you enemy has clones

Chase: This is one of his best breakthroughs, definitely try going only after the Y one, increasing your enemy skill cooldown is an amazing "debuff"

Passive 1: So just summoning 1 more spider per standard attack, it's not a must but it will add some more damage and meat shields for your team

Passive 2: +2 of this passive is really great because it will increase Deidara ninjutsu also with spiders dying. Y one is a bit weird, I wouldn't recommend really using it because you don't really want to have debuffs on Deidara, but if you are going for some kind of full buff nuke team Y would be more useful

In general I'd say 1st breakthrough priority = Y chase

2nd breakthrough priority = Y mystery (depending on team, but generally 40 chakra cost is much easier to utilize)

3rd breakthrough priority = passive 2 +2 (much better buff with spiders dying)

And then the other 2 breakthroughs are quite useful also, but not mandatory to make him an amazing ninja

1. Earth Main

This is the most basic team and can work without his Y mystery breakthrough also, as there is quite a lot of chakra gain

You could also use Earth Main 2x standard attack mystery in this team

2. Earth Main 2

Also a bit of an outdated team but can definitely still work decently

A bit different variation of the team above

3. Earth Main 3

A quite expensive team and would require strong pos2-3 ninjas also

Having Earth Grudge Kakuzu breakthrough also would make him give 2x standard attack also and provide much more efficiency for this team

4. Fire Main

Now this team would require a Y mystery on Edo Deidara to be on the safe side

A very good team with chakra draining + cooldown increase chases while removing all enemy buffs/shields and you will be getting Edo Deidara self-scalling buff over time

Optional talent on fire main = ninjutsu urge or mirror

5. Wind Main

A bit of a change from other teams, using Edo Deidara as a support damage ninja

This team would require strong pos2-3 ninjas to make it more efficient

6. Water Main

Same as the fire main team, only water main version

Water Main provides much more damage over time thru poison, also this team doesn't require Y mystery because you can gain chakra thru Water Main talent from spiders dying.
