Narstad Scrapper

Firebreathing in colorless, with all of that mechanic's liabilities and none of red's reach to back it up. The 3/3 body costs five and does nothing on arrival; the repeatable pump is the whole pitch, converting the eighth and ninth land of a grinding game into points of power and giving a slow deck a use for mana that would otherwise sit idle. There is no ceiling on the power gain, and it applies whether the creature is attacking or blocking, so a stack of activations can turn it into a lopsided combatant on either side of the red zone. What it does not buy is toughness: the base 3 is all the resilience it ever has, meaning any removal or blocker that trades into a 3/3 trades just as cleanly no matter how much mana you have poured in, and the creature collapses to base size the instant you stop feeding it. That makes the pump loud but fragile, a threat that only exists on turns where you have mana to spare and nothing better to spend it on. The Construct typing and artifact status are the only threads pointing anywhere broader, slotting it into shells that count artifact creatures, though the card offers no payoff for that beyond being one. This is fixed-cost filler built as a mana sink rather than a threat, and it makes no pretense otherwise.
