Discount Bloon is an Advanced Blooncard in Bloons Card Storm. It reduces the cost of all Discount Bloons currently in the player's hand by 1 each time it is played, including other charges of the same card.
Having multiple Discount Bloons in the same hand is more cost-efficient and essential to its use as each Discount Bloon played will reduce the cost of multiple Discount Bloon cards instead of just itself.
For My Next Trick can be useful for setting up a cheap swarm of Discount Bloons, if opting for both of those cards in a deck.
Discount Bloons as a rush aren't very threatening, as they're essentially +30 HP Green Bloons with 2 delay. Discount Bloons can be answered fairly easily with cards like Frag Bomb Shooter or Super Monkey Storm.
Discount Bloons give a total of 14 Bloontonium per card, allowing it to be a decent source of Bloontonium. Although this may be a strength, other cards serve this function better while being useful Bloons, such as Golden Blimp, Black Bloon, Zebra Bloon, or BFB.
It is not recommended to run Discount Bloon due to its high cost, slow speed, and lack of stats, making it an active liability in almost every deck.
