What happens if Skill Drain negates Lyla's End Phase effect?✓
Lyla's mandatory End Phase mill effect activates while Skill Drain is face-up.
Negating the effect (not the activation) means it does not activate again. Lyla's End Phase effect resolves under Skill Drain's negation and does not repeat.
If Ryko is flipped under Skill Drain and then Book of Moon is chained, does Ryko resolve?✓
Ryko activates and is set face-down by Book of Moon.
Yes. Skill Drain only negates face-up monsters; once Ryko is set, it is no longer negated and its effect resolves.

● This only negates the effects of monsters while they remain face-up on the field.
If a monster activates its effect on the field, but isn't face-up on the field when that effect resolves (EG, Lonefire Blossom tributing itself), that effect is not negated.
