The Soul of Two

Avatar (When this creature enters the battlefield, put an blue and white Avatar creature token onto the battlefield. Its power and toughness are each equal to this creature's power and toughness. When an ability or counter would be placed on this creature, place that ability or counter on the token. Whenever a spell would target this creature, copy that spell targeting the token. If damage would be dealt to this creature, deal that damage to both this creature and the token. If this creature would be destroyed, destroy the Avatar token.)
