If you are the attacker and you lose, there is no hack. you have a very bad lineup.
You have to undertand the mecanics of the game, how heroes interact each other as a group, and vs you.
Check your runes.
If you do a mirror attack, by using the same heroes for the attacking as the defensive heroes, check the runes the defensive heroes have, and change yours accordingly.
By looking the heroes you used, I can see you used the wrong heroes lineup.
