Desperate Defense is a Basic Powercard in Bloons Card Storm, introduced in version 3.0. It increases the Attack Power of all Monkeys on the player's side by 25 until the start of the player's next turn.
Players should avoid adding too many of Desperate Defense in their decks. It's meant to be a last resort to boost friendly Monkeys, as its name suggests; too many of them may clog the hand at an inappropriate moment if unlucky.
Desperate Defense gives enough of a damage bonus to be useful for all stages of the game. For early stages, it works well with decks with lots of cheap Monkeys such as Dart Monkey Twins, and later in the game allows players to cycle through any excess spare Monkeys to take advantage of the extra damage per shot.
