Well, here's an Idea for some jutsus.
The Yamanaka Clan.
Bloodline Effect.
Level 1-20: +3 to all Genjutsu related rolls, and -3 to all opponent's Genjutsu related rolls.
Level 21-50: +6 to all Genjutsu related rolls, and -6 to all opponent's Genjutsu related rolls.
Level 51-100: +9 to all Genjutsu related rolls, and -9 to all opponent's Genjutsu related rolls.
Jutsus.
-Art of the Valentine: Mind Transfer Jutsu. (Uses a Genjutsu related roll.)
For Success: Both players Random Roll jutsu Power, Users roll must be 10 above Target's. Costs (Chk lvl/5)
-Effect: Takes control of the Target's body for 3 rounds. During this time, the User takes the same amount of damage as the Target. The User may NOT use jutsu the user knows, but may use weapons and items. If the initial roll fails, the user must skip their next round.
-Flavor Text: The Yamanaka clan has developed a powerful spirit release technique, in which can only be used by Yamanaka blood. The user releases their soul and forces it into anothers body, effectively taking control of the target. however, this is a risky move, if they miss, it may take some tme for the spirit to return!
-Protrusion Of Flowers. (Genjutsu)
For Success: User Random Rolls Jutsu Power, and Target rolls Defense. Users roll must be 5 above opponent's roll. Costs (Chk lvl/5)
-Effect: Blinds the target with a flower based jutsu, reducing all Jutsu rolls by the target to have (-1 x Users Jutsu Power/10). Every round this jutsu is in effect, both users must random roll Target's stat average vs Users Jutsu power, if the target's roll is higher, the jutsu is released. The effect of this jutsu does not work with the saving roll.
-Flavor text: The Yamanaka, having an affinity with flowers, classically created a genjutsu in which traps the oppenent in a flower. This sends the senses into overload, causing the affected person to miss with every attempt, and only people with a high willpower can escape.
Note: Just brainstorming, so if someone wanted to steal my ideas for a Yamanaka clan, they could. Feel free to take my ideas, that's why they're here. Also, I would like to see the opinion of others.
