Maelstrom

Maelstrom (メイルストローム Meirusutorōmu) are a series of cards that include "Maelstrom" in its card name exclusive to the Aqua Force clan. The first card was introduced in Booster Set 8: Blue Storm Armada, and the series later received a new member in Booster Set 9: Clash of the Knights & Dragons, along with further support in Booster Set 15: Infinite Rebirth. The series primarily focuses on effects that activate after a certain amount of battles, with the exception of Blue Storm Supreme Dragon, Glory Maelstrom.

All of the members of this archetype are also members of the Blue Storm Armada.
