If you steal Time Warp using Reversal of Supernatural Powers, who takes the extra turn and when does it happen?

Ruling: When you use Reversal on Time Warp, you take control of the spell and gain the extra turn. After your opponent ends their current turn (the one in which they cast Time Warp), you take the extra turn from Time Warp, then take your normal turn.

Sequence:

• Opponent casts Time Warp during their turn
• You use Reversal of Supernatural Powers to take control of the spell
• Opponent ends their current turn
• You take the extra turn granted by Time Warp
• You take your normal turn
