Ceasefire is a Basic Powercard in Bloons Card Storm. It removes all ammo from all Monkeys on the opponent's side. It can be played if the opponent has no Monkeys on their side, or if their Monkeys already have no ammo.
The card artwork depicts a monkey's hand holding up a stick with a white cloth, above a cloud, while many darts and boomerangs are thrown around from opposing sides.
Ceasefire is a more expensive and much rarer Whoops that affects all enemy Monkeys. It's mainly used as a counter to Defenders or Temporary Monkeys (especially Robo Monkey, Corvus Academy of Arts, and MOAB Construction Facility). It is niche but effective against them.
Unlike most removal/sabotage cards, Ceasefire affects multiple enemy Monkeys, but expensive and lacks utility. Thus, it's more of an anti-control card than Whoops, which is more versatile for all types of decks.
Ceasefire cannot stop Druid of Peace’s effect, meaning that for some anti-OTK setups, Ceasefire may be ineffective.
Like Whoops, most players will try to use up all their Ammo on Monkeys that attack Bloons, and using Ceasefire on one reload Monkeys that are not Defenders is pointless.
