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

Edit: I know that a whale from my arena shard (my main competitor for rank 1) is ready to spend money on new packs and get 7 star Krennic and Death Trooper as soon as they are in the shop. I won't spend money on these packs and I want to prepare a team that will be able to beat his new team with these characters.
