Flamerush Rider

Whenever Flamerush Rider attacks, create a token that's a copy of another target attacking creature and that's tapped and attacking. Exile the token at end of combat.

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.)
