I have personally had the highest success rate with a Teebo(L) Rex QGJ EE Fives team. In my last 4 raids, I have managed to do a full p1 solo on the first try 3 times. The time where it failed, I managed to get the captain down to 6%. This team takes around 30-35 minutes to clear P1.
The main advantage of using fives over phasma is the speed down uptime. I find it tends to stay on almost 100% of the time after the initial application. For those without Rex, I have also found that ewok scout is an on-par substitute. No emergency team TM gain like Rex, but he benefits much more from EE basic and Teebo's scramble.
