If a unit with Guardian Angel dies while Zhonya is active at base, do both items get consumed?

Ruling: No, only one item is consumed. When multiple replacement effects (like Guardian Angel and Zhonya) attempt to replace the same death event, the owner chooses which one applies first. Once one replacement effect resolves and recalls the unit, the second effect no longer has a death event to replace.

Sequence:

• Unit with Guardian Angel would die while Zhonya is active
• Owner chooses which replacement effect to apply (Guardian Angel or Zhonya)
• Chosen effect resolves and recalls the unit
• The other effect does not trigger since the unit is no longer being killed

Nuances:

• This interaction works the same way as having two Zhonyas active simultaneously
• Both effects say "kill this instead," meaning once one has been killed/recalled, the other has nothing to replace
