What happens if you react to a Tideturner being played into the base with a bounce effect that removes it from the board before its ability resolves?

Ruling: The Tideturner's ability whiffs (resolves to no effect) if Tideturner is no longer on the board when the ability resolves.

Nuances:

• Tideturner's "original location" is determined when the ability resolves, not when it triggers
• If Tideturner is no longer on the board at resolution, the original location returns as "null" and the ability has no effect
• Gust specifically cannot target bases, only battlefields, so this exact scenario wouldn't occur with Gust
