Enchantment {3}{R}

Card Rules

During each player's upkeep, count the number of permanents. If that number is odd, all red creatures get +1/+1 and mountains produce an additional {R} when tapped for mana until end of turn. If the number is even, all red creatures get -1/-1 and mountains produce colorless mana instead of their normal mana until end of turn.
