Archer's Instinct is an Exotic Powercard in Bloons Card Storm. It allows the player to pick from three cards. The player cannot play this if their hand is full, even if the card only has one charge left. It can only be added to Quincy decks.
Archer's Instinct is best used in the early to midgame to draw out potentially strong cards sooner, especially finishers such as Quick Ready. The caveat is the exclusivity to Quincy.
Compared to other Pick 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 pickable cards 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).
Avoid being at full hand, or else any Archer's Instinct regardless of charge amounts will not be able to be played.
Archer’s Instinct is an extremely powerful OTK tool, as Archer’s Instinct allows Quincy to cycle through a large amount of your deck.
Quincy should use this in most of his decks going later on, due to the sheer amount of cards he can cycle through, allowing Quincy faster OTKs than other heroes.
