RNG for deck shuffling is terrible. In an 80 card deck with 5 cards that have greater than 5 mana cost, I almost always start with 2 of those cards in my starting hand. It makes no mathematical sense.

Game-to-game you see the same cards being drawn over and over and over. The rest of the deck doesn’t play unless you tutor.

Mathematically, this doesn’t make sense. Your shuffling RNG is either broken or inadequate.
