Viashino Blackblades

When Viashino Blackblades enters the battlefield you may pay {2}{g}. If you do,
create a token that's a copy of Viashino Blackblades.

Dash {2}{r}{r}{b} (You may cast this spell for its dash cost. If you do, it gains haste, and it’s returned from the battlefield to its owner’s hand
at the beginning of the next end step.)
