Ashling, The Limitless

Elemental spells you cast from your hand have evoke {4}. (If you cast a spell for its evoke cost,
it's sacrificed when it enters.)

Whenever you sacrifice a non token Elemental, create a token that's a copy of it.
The token gains haste until end of turn. At the beginning of your next end step, sacrifice it unless you pay {w}{u}{b}{r}{g}.
