Quicksilver Elemental + Vivi Ornitier
Overview
If Quicksilver Elemental gains Vivi Ornitier’s 
: Add X mana … ability, Quicksilver has that activated ability and any reference to “Vivi Ornitier” in that ability is treated as referring to Quicksilver Elemental instead (). The acquired ability keeps its restriction “Activate only during your turn and only once each turn,” which applies to the instance Quicksilver gained (, ). Vivi’s triggered ability from casting a noncreature spell resolves before the spell that caused it resolves ([Ruling 2025-06-06]), so that trigger can change power (and therefore X) before you activate the gained ability.

Read the acquired ability on Quicksilver, substituting Quicksilver Elemental’s name for any instances of “Vivi Ornitier” as required by . Thus X refers to Quicksilver Elemental’s power when that ability resolves.
Step 3
You may activate the gained ability only during your turn and only once each turn (the restriction on the acquired ability applies to that instance) (, ).
ability only during your turn and only once each turn (the restriction on the acquired ability applies to that instance) (, ).Step 4
If you cast a noncreature spell that triggered Vivi, that triggered ability resolves before the spell that caused it resolves ([Ruling 2025-06-06]) and may put a +1/+1 counter on Vivi (affecting power) before you choose to grant or activate the ability.
Step 5
If both Vivi and Quicksilver each have that once-per-turn ability (Vivi naturally and Quicksilver via the gain), you can activate each instance once that turn (they are separate instances) ([Ruling 2004-10-04]).
Resolution
When Quicksilver Elemental gains Vivi Ornitier’s activated ability, that ability’s text should be read treating any reference to Vivi Ornitier’s name as Quicksilver Elemental’s name (). X (the amount of mana added) will therefore be based on Quicksilver Elemental’s power when the gained ability resolves. The “only once each turn” restriction applies to the specific ability Quicksilver acquired (, ); you may still activate Vivi’s original ability separately (each instance can be activated once) ([Ruling 2004-10-04]). If the Vivi trigger from casting a noncreature spell is involved, remember that Vivi’s triggered ability resolves before the spell that caused it resolves ([Ruling 2025-06-06]), which can change power/counters before you give or use the ability.
