I got mine at 220 seals. But it was a repeat. From what I understand, it's 50/50 chance to get either as super rare. Even when going for 2 super rares. I'm too afraid to try again, since I might just get repeat super rare one more time.

I got edo Roshi. And I had already bought him long time ago. It was a repeat. There's a chance, that next super rare might be same ninja.

That's why I don't dare to try to get super rare second time.
