Officiele rulings

1/25/2019
Light Up the Stage doesn’t change when you can play the exiled cards. For example, if you exile a sorcery card, you can cast it only during your main phase when the stack is empty. If you exile a land card, you can play it only during your main phase and only if you have an available land play remaining.

1/25/2019
Casting an exiled card causes it to leave exile. You can’t cast it multiple times.

1/25/2019
If you don’t play a card exiled this way, it remains in exile.

1/25/2019
Damage dealt to a player causes that player to lose that much life.

1/25/2019
Spectacle doesn’t change when you can cast the card. For example, you can’t cast a sorcery with spectacle during an opponent’s turn unless another effect allows you to do so, even if that player has lost life this turn.

1/25/2019
To determine the total cost of a spell, start with the mana cost or alternative cost you’re paying (such as a spectacle cost), add any cost increases, then apply any cost reductions. The converted mana cost of the spell remains unchanged, no matter what the total cost to cast it was.

1/25/2019
A card’s spectacle cost is the same no matter how much life your opponents lost or how many opponents lost life.

1/25/2019
In a multiplayer game, if an opponent loses life and later that turn leaves the game, you can cast a spell for its spectacle cost. (If a player leaves the game during their turn, that turn continues without an active player.)
