Shuffle your library. Then exile the top card of your library. Until end of turn, you may play that card without paying its mana cost.

From the Vault: Lore

If the card is not played by end of turn, it remains exiled until end of game.

A copy of a spell can be countered like any other spell, but it must be countered individually. Countering a spell with storm won't affect the copies.

Spells cast from zones other than a player's hand and spells that were countered are counted by the storm ability.

The copies are put directly onto the stack. They aren't cast and won't be counted by other spells with storm cast later in the turn.

The triggered ability that creates the copies can itself be countered by anything that can counter a triggered ability. If it is countered, no copies will be put onto the stack.
