People who don't believe the Dino deck is legit, well, they don't have enough experience in the game. It's pretty dumb when people believe the decks being shared are fake when they are not.

the stream just shows how this deck can make it to kog with just 23 wins. Freaking awesome, but seriously you don't need those floodgates. Maybe the player didn't have Rex @Lvl40.
