Keep one STR Janemba next to Omega Shenron, and the other STR Janemba (try to add them as many as possible from the friend list) always next to Perfect Cell. You can complete the team with Android 18, and two Super STR units that will almost never super attack due to the lack of Ki, like Master Roshi and SSJ2 Trunks, who'll make the others hit harder and therefore compensate for the lack of another Extreme STR hitter (well, Master Roshi works only 70% of the time, but at least he always gives +2 Ki).

And of course, dokkan awaken (and Z-awaken to UR) your AGL Janembas and AGL Syn Shenrons into Super Janembas and Omega Shenrons, respectively.
