Here's a card that has a very specific home, and that's in Burn decks. Light Up the Stage is perfect for drawing more cards, and it does so for only one red mana with its Spectacle ability triggered.
Burn decks have always been very strong, but they often lack a card draw engine. Now the problem is solved, and Burn players will never have to worry about dead draws or flooding.
Unsurprisingly, the card is not too effective in any other types of decks. The reason is that it's a lot harder for Midrange or Control decks to consistently deal damage to opponents in order to activate the Spectacle ability. That's why Burn is the only correct choice for Light Up the Stage.
