Best team to counter new empire team with Krennic and Death Trooper?

You are asking how to beat a team that doesn't even exist yet and is currently impossible to get (not for long tho). Who knows, the team composition could suck and you might beat them easily. Although if I had to guess: not rebels, the anti rebel synergy is too much. Either way, wait until people have had some experience fighting this team, then there might be a direct answer on how to beat it.
