Sand has the two best techniques.
EVER.
Which is?
Bursting sand wall/armor
Put simple, ANY attack launched at it it absorbs, then sends a sand replica back towards attacker.
EDIT:
heres the proper one:
Name: Bakusai Kabe no Suna (Blasting Sand Wall)
Description: The user begins the technique by slamming their hands down on the ground, forcing a wall of sand to rise up to shield them from attacks. This sand wall appears little different from other sand defensive jutsus, but its purpose is quite different. Whenever this sand wall receives an attack, it will absorb the attack completely and then immediately send a blast of sand of equal shape and force back at the attacker. For instance if the target created a concentrated stream of fire (such as in Katon Ryuuka), the wall would retaliate with a concentrated stream of sand, while if a kunai with an explosion note attached was thrown at the wall, the wall would send out a thin line of sand moving as quickly as the kunai would towards the attacker, and then after a short distance it would expand drastically, mirroring the explosion of the explosion note. After retaliating the sand wall will reform properly, unless of course the jutsu the attacker used was too powerful for the wall, in which case the wall will crumble, but only after it retaliates.
Name: Panku Suna no Yoroi (Bursting Sand Armour)
Description: This is an improved version of the sand armour. Instead of simply blocking damage from affecting the users body the armour now actually ‘fights back’. When a blow against the armour is struck instead of simply cracking the armour bursts outward sending sharp shards of concentrated sand directly back at the attacker. The user has no control over how the shards fly but it is extremely difficult and dangerous to attack a person using this skill unless done from a distance.
sands of decay.
When the sands of decay touch something, they begin to eat it away like an acid. The chemical reactions in living organisms slow down this process but non-organic objects are quickly eaten away. The sand does not simply eat away at what it touches but actually continues to spread slowly along whatever it is currently devouring. Submersion in water will stop this spread immediately.
