Flanker, Boston's Blur

Haste, menace

Double Jump — Whenever Flanker attacks,
you may pay {1}; If you do, it gains flying until end
of turn. Whenever Flanker becomes blocked by a
creature, it deals damage equal to its power to that creature before combat damage is dealt. At the end
of combat, if Flanker dealt combat damage to a player or planeswalker this turn, you may return
him to his owner's hand. If you do, draw a card.
