If I use Flash to target 2 units at Dreaming Tree, how many cards do I draw?

Ruling: You draw only one card. Dreaming Tree triggers only the first time you choose a friendly unit at that location with a spell each turn, regardless of how many units are targeted by that spell.

Nuances:

• If both locations are Dreaming Tree and you Flash a unit from each location, you draw 2 cards (one trigger per location)
• The "first time each turn" restriction is per player, so both players can each trigger Dreaming Tree once per turn
• You must move any units you target with Flash (you cannot target a unit and choose not to move it)
