Is it even possible...

[Tiamat]

...to field a competitive all unique heroes army? I'm not talking about in an all heroes format, I'm talking about bringing an all unique heroes army to a standard format tournament. I've only been around for a year, but I don't think I've seen or heard of anyone trying it. Does it happen? Has anyone had any documented success? If it hasn't, do you think one of the known 'upper-level' players could pull it off or would they even be toast going up against a standard mixed build?
