Mana cost :
Create a 3/1 red Elemental creature token unless any opponent has you draw a card. Repeat this process two more times.
Rulings
Development's effect is repeated three times no matter which option the opponent chooses. The opponent may choose a different option each time. You'll wind up with three Elemental tokens, two tokens and a card, one token and two cards, or three cards, whichever your opponent chooses.
In a multiplayer game, each opponent, in turn, has the option to let you draw a card. If no opponent does, you put a token onto the battlefield. Then the process repeats two more times. A different opponent may let you draw a card each time.
A card "from outside the game" may be a card from your collection or a card from your sideboard. In tournament play, you can't choose a card from your collection. The cards you choose don't all have to come from the same place.
The exile zone is a part of the game, so you can't get exiled cards.
A split card's characteristics are a combination of its two halves while it is not on the stack. For example, Assault // Battery has a mana value of 5 while it is in your library. If an effect allows you to search your library for a card with mana value 4 or less, you can't find Assault // Battery.
Each split card has two names. If an effect instructs you to choose a card name, you may choose one of those names, but not both.
Each split card is a single card. For example, if you discard a split card, you've discarded one card, not two. If an effect counts the number of sorcery cards in your graveyard, Assault // Battery counts once, not twice.
If an effect allows you to cast a spell with certain characteristics, consider only the characteristics of the half you're casting. For example, if an effect allows you to cast a sorcery spell with mana value 2 or less from among cards in your graveyard, you could cast Assault this way, but not Battery.
If you copy a spell that's half of a split card, the copy copies that same half. For example, if you copy Assault, the copy is also Assault, not Battery.
Split cards have two card faces on a single card. The characteristics of the half you didn't cast are ignored while the spell is on the stack.
To cast a split card, choose one of its halves to cast. There's no way to cast both halves of this split card.
