I don’t see a lot on this subject yet.
How often are there 2* tournaments? Are they always Rush Attack?
What is your favorite defense team for 2* Rush Attack? What’s your favorite 2* team in general?
Is it worth leveling a 2* team for these events, if, like me, you’re past the point in the game where you disposed of your original leveled 2s? (If you started more recently, the question will be different for you, as you’ll still have your early game team and can simply keep them. At the time I ate my last 2 last fall, I didn’t anticipate that there would ever be a reason to keep them. I miss my old Layla now!) Or are the 2* events too rare to justify that?
