Ice-Heart Coatl

Flash, flying
Playful - When Ice-Heart Coatl enters the battlefield, tap target nonland permanent with
mana value 3 or less. That permanent doesn't
untap during its controller's next untap step.
Dash {u}{u}(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.)
