Come on, this mutation is insane, 1 shotting changelings, 10 kills per bot, how do you expect we win this? i played it like 40 times.
I found lots of guys who completed it with Stetman.
the problem is: not everyone got stetman
raynor + zagara, zagara + karax, you can also use stetman, zaraga can kill propagators with banelings and deal with bots by lings, raynor can deal with propagators with vultures and marines can be given to bots
