Fateful Tempest

Abilities that trigger "whenever players finish voting" trigger once all players have voted or once all secret votes are revealed, but they won't go on the stack until the current spell or ability finishes resolving.

Each player must vote for one of the available options. They can't abstain.

If a milled card has {X} in its mana cost, X is 0 for the purpose of determining its mana value.

No player votes until the spell or ability resolves. Any responses to that spell or ability must be made without knowing the outcome of the vote.

Votes are cast in turn order, and each player will know the votes of players who voted beforehand.

You pay all costs and follow all timing rules for cards played this way. For example, if one of the exiled cards is a land card, you may play it only during your main phase while the stack is empty and only if you have an available land play remaining.
