Bionic Boomerang's On Play effect gives it very strong burst damage. It is very effective for shutting down opponent's rushes during the early-to-midgame, especially with Zee Jay's Rad Enhancements.
Bionic Boomerang has the second highest burst damage from the 1–6 cost range, making it one of the best methods for countering Aggro or early Tempo strategies. The only card with more damage is Robo Monkey with its Defender bonus.
Aggro users should add Gold sabotage cards such as Fright Night or Eco Drain if wanting to avoid an opponent's Bionic Boomerang.
Bionic Boomerang's high ammo on play enables flexible targeting, allowing it to do things like pop two Sentinel Bloons and a Blooming Bloon by itself, even on Dark Castle.
After its initial burst of damage, it remains a strong Monkey that is worth keeping on the field. For instance, it has 5 more ATK than Crossbow Monkey, which also has 2 ammo and 2 delay.
In Boss Battles against Dreadbloon, Bionic Boomerang does great burst damage if Armor is not present. One Bionic Boomerang plus Berserker Brew does enough damage to one-shot Rock Bloons, including Stage 1 Dreadbloon's Rock Bloons from up to phase 3 if they don't have extra Armor, and does enough damage to one-shot Rock Bloons with only Mass Lead Production.
