Invisible woman with agent Venom makes everybody invis.

Invisible woman with agent Venom makes everybody invisible. I have seen this bug a few times already. Invisible woman cast invisibility and everybody on the opposing team goes invisible, until that one tile is destroyed. Might be the best defense ever.

IW's yellow got an upgrade in her recent rework to give two turns of invisibility to her allies and permanent invisibility to herself until the tile is destroyed or cleared.
