2g-iiiii. Conditional Abilities Don't Cancel Base Effects
If an ability fulfills a conditional ability's condition for activation, the latter ability cannot invalidate the former unless its text explicitly says otherwise. For example, a Pre-Battle ability that KO'd the first enemy to KO the Pre-Battle user's allies would not prevent the KO that spawned it - the Pre-Battle ability would activate once the KO had Hit (IE, once it is guaranteed to KO its target if they are vulnerable to it), but before it had Resolved.
