the silvers I use are at L44 E7, and they're just able to handle it. currently I'm working on getting them to level 50, and I suggest you do the same

i'm not sure about the E5 golds' capability to complete the harder battles, but I think it's possible. I would use E7 just to be safe and to make it easier
