How this card plays
Staggered rows enter at different heights and alternate their shots. Change horizontal lanes before the next row reaches the ship. The first warning introduces Claw Pinch. Later volleys alternate between that signature and the formation pattern. Survive three waves to earn a clean clear, or take one free assisted clear.
