Ravnica rare. As formats include more cards, quirky interactions become more likely. Flame Fusillade has been making a splash in the Legacy format because it creates a repeating combo with Time Vault. (As a side note, Time Vault is remarkable because activating its ability involves paying something you don’t have yet! Because you “pay” with turns from the future, Time Vault is one of very few Magic cards to have a cost that basically gets paid on credit!)
