Mardu Whirlscar

Dash {r}{r}, Reveal your hand. (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.)
When Mardu Whirlscar enters the battlefield, it gains double strike until end of turn.
His plan is so obvious he doesn't even feel the need to do as his captain does and yell it to the enemy.
