Fated Conflagration
The triple-red pip is the whole pricing conversation. Five damage at instant speed kills nearly any creature in the game and answers every planeswalker that matters, which is a generous payload for four mana; the cost of that payload is a deck that can produce reliably, which quietly walls it off from anything but a heavily committed red base. That restriction is doing the balancing work that a higher mana value would normally do: rather than charging you more total mana, the design charges you in color commitment, asking you to be a real red deck before it hands you the burn. The scry rider is the cycle's signature, a small smoothing bonus gated behind a turn condition (it only fires on your turn) so that the card-selection upside is reserved for when you take the proactive line. Hold it up on your opponent's turn to ambush a creature and you get the kill but not the dig; cast it on your own turn at a planeswalker and you bank two looks toward your next threat. That tension, between using it reactively for the removal and proactively for the bonus, is the only real decision the card asks, and it is a cleaner one than most removal spells offer.
