Pedal to the Metal

The pump-and-first-strike package has a long lineage in red, but bolting the two together at instant speed with a scalable X makes for a specific kind of tempo weapon. The +X/+0 does nothing for toughness, so this is not a spell that shrugs off a burn response or survives a bigger body's power; its whole output is offense. First strike is the multiplier that makes the raw power lethal in both directions: on your attack it turns a favorable block into a slaughter or spikes an unblocked creature toward a kill, and on defense it lets a small blocker cut down an incoming attacker outright before that attacker connects, since your buffed creature deals its inflated damage first. What it cannot do is out-toughness a trade; durability has to come from killing the other guy before he swings back. The all-power stat line is the honest price of the scaling. Fixed-size combat tricks can afford to hand out toughness because they cap out; a card whose sole output is power, one point per mana poured into X, cannot also grant survivability, or it becomes a one-card blowout with no counterplay. Held up on the opponent's turn it doubles as a bluff and a punish for a greedy attack; cast on your own turn it converts leftover mana into reach. What emerges is a clean late-game mana sink for red: no cards drawn, no board added, just a burst of damage that asks you to already have a creature where it counts.
