Delay

You send the actions of a creature into the near future, away from the present. Choose a creature within range you can see.  It must succeed a Constitution saving throw against your Spellcasting DC. On a failure, the target forfeits their turn this round, however in the next round they will have two consecutive turns. On a success, the creature forfeits their movement for this round and next round they will have a doubled movement speed for that round only. 

The target can willingly fail. You cannot target a creature whose turn has already taken place this round.
