You probably know what the rules of a dream team are.
Apply them to EB and we have a fun discussion.
So the basic concept is you have 20 unit slots to make an army and you have no limits as to what you can choose - you can choose units from any factions, with no price limit and any amount of duplicates. For example you could have all your cavalry parthian and all your infantry roman triarii or something crazy like that... Imagine the flanking you could do with that.

So just post some lists of perfect/weird/funny/brutal armies so we can speculate and say "What if...".
