*In midrange decks, Bloonsday Device can be used to deplete the opponent's tempo, resetting the board so you can begin your own tempo in the next turns. However, avoid using it if your tempo is better than theirs.

Moreover, its playstyle disincentivizes playing offensive Bloons (except the Eternal, which is fine with Bloonsday Device). Because of this, using a Bloonsday Device will break Dreadbloon's momentum, allowing time to attack with Monkeys or recover from a board-wide Monkey removal.

Update history

  • Nerf Gold cost increased ― 15 → 18

Development

During Version 6.2 playtesting, the nerfed Gold cost from 15 to 18 was decided due to its impact at limiting the choice to play other cards before affording the hard counter that would "destroy all Bloons", making it more predictable to anticipate and more risky to use early on.[1]
