The so called “random” effect of the spell: make an enemy minion health to 1 ALWAYS targets the biggest one. Lost to this spell more times that i can count. This kind of spell will make people leave hearthstone forever.
I’ve had it target the lowest health minion many times. It is no less random than any other random spell in the game.
Even if it’s true… why don’t you have two or entire board big?
Why don’t you use that spell too??
You can cry or find a better way to play.
Success or the same Failure over and over again.
It’s easy, your choice.
