How do you beat Phoenix squad in arena?

I used to run Phoenix and I struggled to stay in the top 500, then I made the Nightmare team of EP, Vader, Sion, Thrawn, and Nihilus and I've been consistently top 100 and occasionally top 50 ever since. It's definitely the best and easiest f2p meta team out there. To anyone running Phoenix in arena, get them to around G9 and they'll get you both Thrawn and Palpatine; Vader is pretty easy to unlock through achievements, hard to max though but tanky enough to survive at lower stars; Nihilus is a tough farm for lower levels, but one of the special events (also requiring Phoenix) gives his shards, and he's viable at 3*; Sion also has tough nodes to farm, but he's great even at 3* if you unlocked him in the marquee event. It's really not that hard of a team to make, and if you already have a good Phoenix, they will get you both of the legendary characters.
