The editor who added this notice elaborates: Combination aggro for Bloonsday? Why? Price nerfs makes it even more geared to control decks
This section was last updated for: version 6.2
  • Bloonsday Device is designed with control decks in mind, and is a counter to midrange and tempo decks if obtained soon enough. Both players have their Bloons completely destroyed, unlike any other board clear, and the most expensive with only one per deck.
  • Obyn Greenfoot and Mountain Obyn gain a whopping 225 Shield when pulling this with Nature's Clarity, which helps greatly in defending.
  • 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.
  • Since OTK decks don't really care about the Bloons they have on the board until they win the game, they are free to use this whenever they like (assuming they don't need 20 Gold next turn).
  • Bloonsday Device shuts down decks designed to kill with one giant push, such as ZOMG + Double Trouble spam decks or Lead Coating Bloon + Armor Powered Bloon decks.
  • Combination aggro + OTK decks can use this against tempo and midrange decks to cancel potential counterpushes, buying more time to draw for a bigger combo or perform a final push.
  • Dreadbloon has a tendency to build up and string constant pushes of high delay Bloons, supported by its 80 card Deck, powerful removal, and Rock Bloons. Moreover, its playstyle disincentivises 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.
  • As an Ultra Rare, it can be drawn by ULTRA Rare Power, in fact a reliable way to obtain it. Even at max Gold, it's still too expensive to combine it on the same turn.
  • Bloonsday Device can be used to cancel a Red Bloon Apopalypse, to clear space for Storm Bloons.

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]
