At the beginning of your upkeep, choose one at random. Create a red and white creature token with those characteristics.
• 3/1 Human Warrior with trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.) and haste (This creature can attack, and as soon as it comes under your control.).
• 2/1 Human Cleric with lifelink (Damage dealt by the creature also causes its controller to gain that much life.) and haste (This creature can attack, and as soon as it comes under your control.).
• 1/2 Human Rogue with haste (This creature can attack, and as soon as it comes under your control.) and "When this creature enters the battlefield, it deals 1 damage to any target."
