Super 17 can defend well, and after being hit five teams he gets the same ATK boost as TUR Cooler and Rosé.

If you're interested in a full Extreme PHY team, you could use the Android 17 that dokkan awakens into Super 17 (his links get a lot better after dokkan awakening, but they work mostly with Omega Shenron, so at the moment you'd only use his orb changing skill), King Cold debuffs the enemy and shares a Ki link with both Cooler and Frieza, and Fat Buu is a healer. Nappa could also be an option, he dokkan awakens into a better Ki support unit (and leader, but you don't need that).

You can still use units that aren't going to benefit from any leader skill, but they might be a problem when it comes to defending (depending on the difficulty of the event), and your HP as a whole would also be lower.
