Bolstered Bloon
Shield 50. Gain 25 Health each time you play a Bloon
Bolstered Bloon is an Advanced Blooncard in Bloons Card Storm. It starts with 50 Shield when it is played and it gains 25 Health each time the player plays a Bloon. Some actions that spawn Bloons on the player's side, like the Storm Bloons, do not trigger this effect. Revive, however, does.
Due to its slower speed, Bolstered Bloon generally is a less effective Bloon than other options. Bolstered Bloon can be a threat when combined with many bloons. Spamming multiple cheap bloons is an easy way to accumulate extra health for the Bolstered Bloon.
It is best to wait to have other bloons in your hand when playing Bolstered Bloon to ensure that it isn't instantly popped after it is played.
Bolstered Bloon is best used in Aggro decks, many of which include lots of cards with cheap, spammable bloons. Generally, the best moment to start Bolstered Bloon is Round 3 (Round 2 on High Finance) and follow up with as many cheap-costing bloons as possible.
Having at least two other bloons will ensure that double Storm Of Arrows won't guarantee hitting the Bolstered Bloon twice.
Keep in mind that countering a Bolstered Bloon in the early-game is not very difficult. Hero Protection or Return to Sender can counteract the damage from a highly boosted Bolstered Bloon.
Bolstered Bloon falls off quickly, as saving up for a turn or two allows players to have better access to expensive board clears such as Thunder Druid and burst damage such as Super Monkey.
Versus an Aggro mirror, Bolstered Bloon is generally worse than other options. It relies a lot on luck, depending largely on beginning with Reds and Bolstered, and generally has a worse reward than cards like Blooming Bloon.
Aggro decks that run Return To Sender to counter ARBITR have a major advantage versus Bolstered Bloon.
Running Zombie Bloons can help Bolstered grow quickly with repeated triggers. Run them over Nested Bloons as they provide more value.
