Vigilance (Attacking doesn't cause this creature to tap.)
Whenever Warden of the Woods becomes the target of a spell or ability an opponent controls, you may draw two cards.
An ability that triggers when something becomes the target of a spell or ability resolves before the spell or ability that caused it to trigger. It resolves even if that spell or ability is countered.
Players can cast spells and activate abilities after the triggered ability resolves but before the spell that caused it to trigger does.
