Archer's Instinct is an Exotic Power card in Bloons Card Storm. It allows the player to pick from three cards. The player cannot play an Archer's Instinct card if their hand is full. It can only be added to Quincy decks.
Archer's Instinct is best used in midrange to draw out potentially strong cards sooner, especially finishers such as Quick Ready and core cards such as The Eternal. The caveat is the exclusivity to Quincy.
Compared to other Pick X cards, Archer's Instinct is the cheapest and comes with two charges instead of one, but has no special effect based on the card picked. It's also rarer than Adora's Divination.
Compared to Amelia, Quincy has the most possible Pick X via Archer's Instinct, even with Amelia's For My Next Trick and Bubble Time! (up to 30 via three of both cards, vs 36 with three Archer's Instincts).
