Strategy

For more in-depth strategies, see Strategy:Finn (BATTD).

When starting out, Finn is primarily an early-game character that can help clear the early rounds, but struggles once MOABs appear.

However, if the player has Missile, it synergizes well with Finn's Bound by Word as it affects Missile, which when made permanent with Royal Promise, makes him the best character for the Missile, letting him clear out MOABs with ease and heavily damaging the BAD. With this build, it is highly recommended that attack speed trinkets and weapons, such as Finn Sword and Baker's Shard, are stacked in addition with the Missile, for making the Missile attack as often as possible.

There is a bug with Finn that makes him very useful for farming later on, as once he unlocks Big Hearted Hero, he can skip hundreds of rounds on most maps, claiming all Martian Games round milestones and clearing Impoppable in a minute. This glitch requires Finn at level 7, and is performed by leaking at least 2 bloons while he has Big Hearted Hero purchased, then rapidly pressing the start round/speed up button after leaking enough lives to activate Big Hearted Hero. Using an autoclicker is recommended for this for making it more consistent.

While Bro Fist can be used for income when starting out, Finn is much better used for the aforementioned Missile and Round Skipping builds instead as the player acquires more trinkets. Thus, Eco Finn is not recommended if they have other eco characters, as C4 Charlie, Warrior Bubblegum, and Marceline are much better suited for eco builds for his higher income potential for the former, or their lack of other good builds for the latter two.
