I think the game is definitely rigged. You can't watch the opponent's first 4 attacks with AI-like precision dismantle your board doing a 1 in 700 sequence of events several times and come to the "it's just random" conclusion.
It's clearly not always random.
Do they do this to shorten the games? To make the games more exciting?
So the important thing is to have Taunts to somewhat suppress the ability of the game to screw you.
You not understanding how random things work is not the same thing as said randomness not existing.
