If a unit would be destroyed by Volibear's ability during the initial chain of a showdown, does it die before the player can use actions?

Ruling: The unit dies as part of the initial chain due to Volibear's ability. You will still get to play actions during the showdown, but you won't have any units at the battlefield at first.

Sequence:

• Volibear's ability triggers during the initial chain
• The unit dies before actions can be played
• Players still get to play actions during the showdown
• The player whose unit died starts with no units at the battlefield
