Ninja Effect Chains and Status Changes

[Elite]

Suppose I have a N-US006 Sakura Haruno [A Double Personality] battling against my opponent's PR-US008 Gaara of the Desert [Tragic Name] and N-US001 Naruto Uzumaki. During the Exchange of Jutsu, I use Sakura's effect. My opponent then chains to it with Gaara's effect. If Sakura and other non-valid ninjas are injured or removed from play with their ninja effects on the chain, does the ninja effect still resolve?

[Mr Wheat]

the Ninja effect will not be applied, since when the "Valid:"-ity of the effect is checked at the time the Ninja effect is to be applied, it will find the non-"Valid:" Ninja in injured status.

similar to the rule that a Ninja user must be on the Battlefield when a Jutsu is used and when its effect is to be applied, a Ninja using a non-"Valid:" effect must be healthy when the effect is first activated and when the effect is ready to be applied.

this applies to what we will be calling a regular Ninja effect.

Continuous, Replacement and Interrupt Ninja effects will have their own set of rules for their unique situations.
