Tanak's Storm

At the beginning of each upkeep and each end step, Tanak's Storm deals 4 damage to each creature. If a creature dies this way, draw a card.
At the beginning of combat on each players turn, if they control more creatures then each other player, creatures they control gain protection from Tanak's Storm until the end of their next turn.
The Storm makes it so the rival groups have a fair shot at the throne.
