Black Hole

Black Hole is a zombie environment from the Hearty class. It costs 1 Brain to play. It is a Super-Rare Galactic card.

Plants within it have -1 Strength. When a Plant is played, it moves to its lane, unless the lane is full. If possible, plants will be moved in front of the already present plant. When multiple Black Holes are in play, plants will be moved to each from left to right, regardless of the plants placement.

Strategies
Placing a Black Hole in the latest lane possible will ensure that your zombies will attack before the plants, sometimes giving you the upper hand.

Placing a zombie with frenzy, armored and/or high health is a good move, as it is both good for offense and defense.

Placing a non-Team-Up plant in a Black Hole stops other plants from being sucked into it.
