As a free source of Bloontonium, this card helps if the player's deck heavily relies on Bloontonium.
Heroes with more expensive abilities, such as Gwendolin, will benefit further from the free Bloontonium.
Amelia may benefit from Bloontonium Cache to begin aggro with lots of durable bloons such as Steady Growth Bloon, to access Bloon Shield sooner.
Quincy for aggro decks benefit from earlier access to his passive and Flurry of Arrows sooner, particularly against an aggro mirror.
Vital for Zee Jay aggro, as now each bloon will gain up to +25 HP headstart, which is certainly worth drawing first in addition to gradually drawing bloons.
