Tempest

Buyback o2 (You may pay an additional o2 when you play this spell. If you do, put it into your hand instead of your graveyard as part of the spell's effect.)
Put the top creature card from your graveyard into play. That creature is unaffected by summoning sickness this turn. Remove the creature from the game at end of turn.

Corpse Dance only exiles the card if the card is still on the battlefield at the beginning of the end step.

The effect only grants Haste until the end of the current turn. If the creature somehow manages to stick around until a later turn, it will no longer have Haste.
