Steppe Sliver

Each sliver card in your hand has dash {2}. (You
may cast a sliver 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.)
Dash {2}
The sliver raced across the Tarkir steppe with startling
speed. Within days, not even the Mardu could outrun
the sliver hive.
