The Cobra King [Unknown Event]

At the beginning of each player's upkeep, create a 1/1 blue Serpent creature token named Cobra Coil. When you do, if you control five or more Snakes and/or Serpents, choose one —
• Strike first — Target Snake or Serpent you control fights target creature an opponent controls.
• Strike hard — Put a +1/+1 counter on each Snake and Serpent you control.
