If I have a unit and a hidden Tide Turner at a battlefront, and my opponent attacks that battlefront and uses Fight or Flight on my unit, can I wait for Fight or Flight to resolve before using Tide Turner to swap the unit back to the battlefront?

Ruling: Yes, you can wait for Fight or Flight to resolve before using Tide Turner. You maintain control of the battlefront until the end of the combat showdown, so your hidden card is not discarded until after that point.

Sequence:

• Combat opens at the battlefront
• Fight or Flight resolves during combat
• Combat showdown occurs
• You can use Tide Turner anytime before the combat showdown ends
• Once combat showdown ends and resolution begins, you lose control and the hidden card would be discarded

Nuances:

• Deathknell triggers during resolution can create additional opportunities to act before losing control
