Wow, you must be pretty lucky in free summons then. The only good thing I've gotten was a Gaara from free summon...

Anyways, I don't have experience with Earth Mains, but I've definitely studied many Earth mains, while fighting them. I honestly don't how many Earth/Fire mains there are in my server; too much to count, that's for sure. :L
Maybe you could try a Main/Kisame/Kurenai/Tsunade formation?

Like this one?

With this skillset?


I apologize in advance if it doesn't satisfy your requirements. :dizzy:
