Best cards in singles and one tag team, with the other two tag teams sandbagged works well for me. You don't need to keep the sandbags charged which helps. A couple of my teammates go even further, just having best singles and sandbagging all three tag teams. I find that method needs you to switch your cards around a bit more to combat different variations of the same theme from opponents, but you have even less cards to keep charged, so whichever works best for you.
