Double Trouble is an Exotic Powercard in Bloons Card Storm. It creates a copy of a target Bloon on the player's side. The clone will inherit all properties of the parent (including Health, Delay, Shield, and status effects). If the target was played by the player, and not from the Storm, it generates Bloontonium equal to its cost and triggers any On Play effects when it spawns.
Double Trouble stands out for OTK strategies, duplicating a 0-delay bloon for further damage. Double Trouble can also be used to duplicate a powerful bloon for extra pressure.
If performing a combo with Double Trouble, duplicate a bloon after buffing it, not before.
Combos with Double Trouble can be expensive. Quincy Action Figure and Obyn Greenfoot offer more leverage to affording one-turn combos costing greater than 20 Gold.
Duplicating a played Bloon (i.e. not from the Storm) generates Bloontonium as if that bloon was played again. This tactic can be used as another source of Bloontonium while applying more pressure to your opponent.
The Eternal can be copied so that it's harder to single out each copy of it.
