When both players target their own friendly units with spells during the same showdown (one with an action, one with a reaction), does The Dreaming Tree trigger for both players or only the first player to target?

Ruling: Both players draw from The Dreaming Tree. The "first time" refers to each player's first time targeting a friendly unit, not the first instance across both players.

Sequence:

• Player A plays action targeting their unit
• Player A draws from The Dreaming Tree
• Player B plays reaction targeting their unit
• Player B draws from The Dreaming Tree
• Effects resolve in reverse order

Nuances:

• The wording "a player" tracks each player individually rather than limiting it to one draw total across both players
