I used earth wall Not HArdening .. To stop ur clones comming close thus blocking kunai's too
I dont know whether this will work As PYRAMID OF DOOM is KO move =/
But here gos nothing ..
As i see ur clones surrounding the rampart I use
(Doton: Iwa Yado Kuzushi) - Earth Style: Stone Lodging Destruction ( DONE )
Rank: C
Type:Supplementary
Range:Short-Mid
Chakra cost:15
Damage Points:N/A
Descripton:This technique allows the ninja to control nearby stone and rock. This can be especially useful if in a cave or a stone lodging. The technique can loosen the rocks and cause them to come raining down on whomever is trapped inside.
Thus bombarding them with Rocks of bigger Size thus distracting them and making them loose their positions .
P.s If that works then as me and my clones are falling MY clone 1 uses
(Doton: Doryuu Heki) - Earth Style: Mud Wall ( DONE )
Rank:B
Type

efence
Range:Short
Chakra cost:20
Damage Points:N/A
Descripton: The ninja will do the necessary hand seals and then spew a line of mud onto the ground. The mud will then grow into a large mud wall to help defend against incoming attack.
Thus all 3 of us land on the wall ..
Then Clone 2 uses
Chidori Senbon (1000 Birds Needle) ( DONE )
Type:Attack
Rank: A
Range:Short-Mid
Chakra cost:30
Damage Points:60
Descripton: Chidori in the form of needles that can be thrown to pin down an opponent or
to injure them.
To kill ur clones
