Post-match analysis.

The wording is strange. Are we talking about Facebook? Well, that will still depend on how you conduct it. Plus, there's magic, stats, and a lot of other things (artifacts, terrain type, etc.). If we're talking about "balancing," then it should be done with troops that have similar speed to those of the opponent. Or have the right magic.

P.S.
I suggest balancing angels with Implosion – it's reliable. As a last resort, Cursed Armor will also work. :D :D
