Does Light-Imprisoning Mirror negate Archlord Kristya's return-to-Deck effect?✓
Kristya leaves the field and Light-Imprisoning Mirror is face-up.
No. Light-Imprisoning Mirror only negates activated effects, and Kristya's return-to-Deck is a continuous effect that does not activate.
Can Light-Imprisoning Mirror be chained to Ryko flipping, and does it negate Ryko?✓
Ryko is flipped face-up by an effect or by battle and Light-Imprisoning Mirror is set.
Only if Ryko is flipped outside the Damage Step, Light-Imprisoning Mirror can be chained and will negate Ryko. If Ryko is flipped by battle, Mirror cannot be activated in the Damage Step.

● This doesn't stop monster effects from activating.
It just negates any effect which does activate (on the field/GY).
● Even if the Physical card is no longer on the field/GY, the effect is still negated.
