Eerie Lifeforce is an Exotic Powercard in Bloons Card Storm, introduced in version 6.0. It increases the Delay of the selected Bloon by 1 and gives it +10 health per Bloon in the player's graveyard. If there are no Bloons in the player's graveyard, it still adds delay to the target, but does not add any health.
Despite having the Stunned keyword, the Bloon doesn't actually get stunned; this is a remnant of a balance change in version 6.2.
The card artwork portrays a Ninja Monkey at a graveyard getting stunned by the ghosts of multiple Bloons during nighttime.
With enough Bloons in the graveyard, Eerie Lifeforce on a friendly Bloon can act as an alternative to Improved Fortification for less cost. Using it on the opponent's Bloons can be done, but the Health gain means that doing so should be only used early or as a last resort to stall the Bloon before a card such as Return to Sender.
Like Improved Fortification, Eerie Lifeforce can be used to make an OTK combination, and Immobile Bloons don't care about delay.
ARBITR can be used if the opponent lacks anything strong enough to stop it.
Similar tactics to strengthen a friendly Double Yellow Bloon before using two Quick Ready can be done. Double Yellows from the Storm are still easier; playing a Double Yellow plus those cards would cost 21 Gold.
Eerie Lifeforce can be held for a long period of time to give late game Bloons an obscene amount of health for 2 Gold.
Before using this card, check how many Bloons are currently in your graveyard by tapping the deck icon on the bottom-left corner to view it.
Eerie Lifeforce can be used early on by decks that don't play many Bloons to stall enemy Bloons.

Development
This card originally added 10 Health per Bloon in the graveyard, but it was increased to 20 health per Bloon before the update released due to feedback from community playtesters.[1] The original amount was displayed in the update video.[2]
Eerie Lifeforce had multiple aspects addressed during its testing in Version 6.2 playtests. The main issue was that stun on friendly Bloons lasted effectively two turns, so it would take forever to the Bloon to attack. Instead, the stun was changed to a delay increase,[3] considered an overall buff[4] by community playtesters due to the effect being able to be used with Quick Ready.[3] This brought another development that community playtesters noted, which is that the Health gain was extremely powerful to the point that aggro would use Eerie Lifeforce on their own Bloons,[3] and leaving it as is would make any archetype too strong as the scaling made any deck that ran even a decent amount of Bloons have a very strong win condition.[3] Eerie Lifeforce was then nerfed from +20 -> +10 health per Bloon, which made it into the final game.
