Electrical Apparition

If Electrical Apparition wasn't dashed, it deals 2 damage to target creature or player.
Dash {r} (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.)
If you chose to pay Electric Apparition's dash cost, it becomes a 2/2 Elemental creature with trample until it leaves the battlefield.
