If both players are at 7 points during turn 5 of overtime and you control a battlefield and cast Time Warp, do you win or does the extra turn not work?

Ruling: You do not get a 6th turn in overtime. The game ends in a tie.

Sequence:

• If Time Warp is cast on turn 4 of overtime, you would get the extra turn 5
• If Time Warp is cast on turn 5 of overtime (the final turn), you do not get a 6th turn
• The game ends in a tie when overtime turn 5 concludes
