3v3 battle

[Yawgmoth]

3v3
Arena: Short grass, a few rocks here and there, and a small river in more or less the middle.
You send out and choose attack first.
Standard rules.

Any takers?

[Psyshadow]

Sure, I'll battle you. But we need a ref for the battle. Any takers for a ref position?

[Chris 2.1]

Since Psyshadow has been banned, can I battle you?

I don't understand, though, how I order my attacks first when I don't know what I'm fighting ^_~
