Combo Nicol Bolas, God-Pharaoh +Jace, Cunning Castaway +Oath of Teferi
You can cast Nicol Bolas, activate his +1 ability, and then leech Jace’s -5 ability. This creates two copies of Bolas, and then the same process turns them into four, eight, sixteen, and so on. That’s the unlimited power that the Dragon-God was after, and if you keep activating his own +1 ability along the way every time, your opponent is left with no cards in hand and no permanents on the battlefield.
