He played his whole turn doing that. Now you play your turn, now that you're ahead since he had an empty board, therefore couldn't trade, giving you the option to value trade, board clear and go face, or just straight up go face for free damage.
That's not even counting the times where your board could just be utter garbage for someone who doesn't have board buffs(which you can now use your 6 mana to give +2/+2 if you're a token druid deck, or savage roar x2 savage roar for 16+Minion's base attack to face, for example), not even counting the good chance he randomly got the two worst cards on your board.
