Yellow Bloons can naturally spawn from the Storm, always spawning on Round 4 (Player 2) and Round 5 (Player 1). Arcane Master generates a Yellow Bloon with 1 charge whenever it reloads.
Yellow Bloon is a decent choice for both aggro and midrange decks. Their high health per cost forces a response from a player without defenses or healing.
Quincy can use Storm of Arrows against a Yellow Bloon, and optimally when there is another bloon around its health range.
Because of its 130 HP, a Quincy's passive plus either 4 Arrow Shots or a Storm of Arrows card will fully pop a Yellow.
