This may be the most underrated of the Silvan return to hand events. I find that in most quests at least one shadow effect shows up that will have a devastating impact (additional attack, return to staging, deal one damage to a 1 hp defender, etc.) if not dealt with.
Quicker Than Sight provides a simple solution for Silvan decks without requiring any resources (giving it the advantage over Hasty Stroke). It has the added benefit of bouncing back a Silvan (Galion is great for this!) to be replayed later, and it can cancel any shadow effect (not just for enemies engaged with you).
I typically throw 1-2 into Silvan decks with access to . Really solid card.
