Crystalline Resonance

If an effect begins to apply to Crystalline Resonance before it becomes a copy of another permanent, that effect will continue to apply.

If Crystalline Resonance becomes a copy of an object with a set of linked abilities (for example, one ability that exiles a card and another that refers to the card “exiled with” the object), that link only lasts as long as Crystalline Resonance is copying that object. If it stops being a copy of that object and then becomes a copy again later, the link is lost.

If Crystalline Resonance becomes a copy of an Aura, it’s put into its owner’s graveyard unless it’s somehow attached to an appropriate object or player already. If it becomes a copy of an Equipment and is attached to a creature, it’ll become unattached when it becomes an enchantment again.
