How does Timewarp interact with Overtime's 5-turn limit?

Ruling: Timewarp adds an extra turn for you that counts as one of the 5 turns in Overtime. This means your opponent gets one fewer turn in the Overtime sequence.

Sequence:

• Turn 0: Your turn
• Turn 1: Opponent's turn
• Turn 2: Your turn (play Timewarp)
• Turn 3: Your extra turn from Timewarp
• Turn 4: Opponent's turn
• Turn 5: Your turn

Nuances:

• If you play Timewarp on turn 5, the game ends at the end of turn 5 and you don't get the extra turn because the game is already over
