9 rulings from Wizards of the Coast
- 18 July 2014To activate the first ability, you must target a player but you can choose to not target any creatures.
- 18 July 2014While resolving the third ability, you create the copies of the card in exile and cast them from exile. You can cast zero, one, two, or all three copies. The card itself isn't cast. It remains exiled.
- 18 July 2014Because you're casting the copies "without paying their mana costs," you can't pay any alternative costs for the copies. You can pay additional costs, such as kicker costs. If the copies have any mandatory additional costs, you must pay those.
- 18 July 2014If you exile a land card using the second ability, you may play that land only if you have any available land plays. Normally, this means you can play the land only if you haven't played a land yet that turn.
- 18 July 2014In the third ability, "exiled this way" means the cards you just exiled because of that ability resolving. Cards exiled with the second ability or with previous activations of the third ability don't count.
- 18 July 2014If the first ability resolves but the damage is prevented or redirected, the target creature still won't be able to block that turn.
- 18 July 2014The card exiled by the second ability is exiled face up. Playing it follows the normal rules for playing that card. You must pay its costs, and you must follow all applicable timing rules. For example, if it's a creature card, you can cast it only during your main phase while the stack is empty.
- 18 July 2014If the copied card has {X} in its mana cost, you must choose 0 as its value when casting the copies.
- 18 July 2014While casting the copies created by the third ability, timing restrictions based on the card's type (such as creature or sorcery) are ignored. Other restrictions, such as "Cast [this spell] only during combat," are not.
