The Emboldened Bloon is a Large Blooncard in Bloons Card Storm. Its Gold cost is reduced by 1 per Bloon currently in the player's queue. It can reach a minimum cost of 0 if all slots are filled, but that prevents the Bloon from being played, so its actual minimum cost (before discounts) is 1 Gold in practice.
Emboldened Bloon, just like Bolstered Bloon, needs swarms of bloons to be efficient, the main differences with Emboldened Bloon are that it becomes cheaper as the Emboldened Bloon is sent deeper in the queue, and its health doesn't scale with extra bloons.
However, Red Bloon Storm stops the Emboldened Bloon from being placed. While still possible with two Arrow Shots from Quincy or a Bloon Melter to pop a friendly Red Bloon, this is impractical.
Having lots of cheap bloons sent before the Emboldened Bloon will save the most money. Swarm Reds, Reds, Blues, and Swarm Blues are recommended to fill most of the board.
This card can be used in midrange play-styles to some effect, as the slow Bloons the archetype usually plays naturally stay on field long enough to make Emboldened cheap.
Some players may use Emboldened Bloon's cost scaling to alter Bloontonium gains from playing this Bloon.
