Ollie Barry and Kara have all encountered that kinda attack before. All of them were able to snap out of it before inflicting damage...Meh, I got Team Cap. Three actual soldiers, two enhanced and one a master tactician, a long range assassin, and Wanda's reality warping abilities.
Wanda alone is enough. She can have everybody attacking one another by making them think they're the enemy and she doesn't even need to be close up on 'em to do it.
That attack only works effectively on weak minded... Kinda like the force.
Also Wanda has never displayed any kinda durability. She got knocked out by the reign fire in endgame. She was getting dragged in the beginning of infinity war before cap showed up.
And even in MoM she never showed much resistance to physical attacks that actually touched her.
Kara and Barry are fast enough to touch her....
And unless Ollie is crazy distracted.... Which he might be... He'd see the opening.
Honestly I think Ollie is a better leader than both Tony and Cap.... The whole premise of civil war was that the team divided.....
Ollie brought everybody together every single time. Even when they knew he was dead ass wrong... Niggaz followed Ollie into war. .
His team was giving no fucks. The avengers stay pulling punches
