Super 17 is a +120% leader (+100% in your case), so it should be extremely easy with him. Units that "lower the enemy's DEF" can break Broly's barrier (which is just a high defense), and Super 17 greatly lowers the enemy's DEF. Android 17 also lowers the enemy's DEF. And if you can't find a Super 17 friend, you can use Rosé instead, he's also Extreme AGL and he also greatly lowers the enemy's DEF. Critical attacks work, too, since they ignore the enemy's defense.

Plus, Super 17 shares two Ki links (+4 Ki) with Oceanus, who seals the enemy's super attack.
