William, Court Jester

Haste
When William attacks, choose Comedy or Tragedy:
• Comedy — Put a more counter on each other creature. (If a triggered ability of a permanent with a more counter on it would trigger, remove a more counter and it triggers one more time.)
• Tragedy — Put a less counter on each other creature. (If a triggered ability of a permanent with a less counter on it would trigger, remove a less counter and it triggers one less time.)
