Shifting Tides triggers at the start of your turn if it is in the arena. You must pitch the top card of your deck
When you pitch cards this way, you may still trigger effects due to pitching and you still gain the resources from pitching (e.g. you would gain resources equivalent to the pitch value of the card). Cards without a pitch value (e.g. Gorganian Tome, Goldfin Harpoon) do not generate any resources when pitched.
Neither player receives priority during the start phase of a turn.
If a card that is being pitched is in a private state, it is shown and made public first before it is moved to the pitched zone. if you are under an effect that says you can’t pitch a specific card (e.g. Chains of Eminence, Null Time Zone) you will not be able to pitch that card and will be put into the graveyard by the subsequent effect.
If you do not pitch the top card of your deck (e.g. your deck zone is empty), you will destroy Shifting Tides.
If you don’t have any cards in your deck zone when resolving this effect, it will become the only card there.
