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.

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.

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