Ground Rift — ruling 1

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.

Ground Rift — ruling 2

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

Ground Rift — ruling 3

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.

Ground Rift — ruling 4

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.

Ground Rift — ruling 5

You may choose new targets for any of the copies. You can make different choices for each copy.
