Why the game is not making money

I am playing a druid right now. 1 mana crystal 1st turn on their part. They have played 2 cards that cost 5 and another maganitierzer card. by mana crystal two they have 4 big cards on the boards soon to be buffed up to a million damage.
no way to beat this.
Can the devs explain what they were thinking when they designed this?
Update, by turn 4 they had the entire board covered everything had a deathrattle and buffed up to a massive amount of damage.
Crazy huh.
