Genesis Storm

If you choose not to put the nonland permanent card you reveal onto the battlefield, you’ll put it on the bottom of your library with the other cards.

The copies are created on the stack, so they’re not “cast.” Abilities that trigger when a player casts a spell (such as the Storm’s ability itself) won’t trigger.

Each Storm’s triggered ability counts only how many times you’ve cast your commander from the command zone before that triggered ability resolves. If you cast your commander again later, you won’t get another copy.

If your library no longer has any nonland permanent cards, you’ll reveal your library and then put it back in a random order.
