Scruffy, Wild Wizard

You must pay {p/r} or {p/u} rather than paying
generic mana costs.
You cannot gain life.
Whenever you cast an instant or sorcery spell,
you may deal 4 damage to any player. If you do,
that spell deals 2 damage to you.
Spells with mana value greater than 6 cost {p/r}{p/u} more to cast.

wizards anymore?"
