Droideka

Dash {2}{r} (You may cast this card 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.)
{3}: Droideka gains indestructible. It must attack
this turn if able. Activate this only as a sorcery.
As long as Droideka is indestructible, it doesn't
untap during its controller's untap step.
