Daxia, the Accursed

Whenever you cast an enchantment spell, you
get an experience counter.
{1}{w}{b}: Put a white and black Spirit
enchantment creature token onto the battlefield.
It has "This creature's power and toughness are
each equal to the number of experience counters
you have."
"For each curse I bestow unto thine, brings me ever
closer to the end of mine."
