Razorfield Thresher

Seven generic mana for a 6/4 with no abilities is, by any standard the game has held since its early years, a non-functional rate: this is colorless filler from a design tradition where artifact-dense sets needed bodies that any deck could cast to round out a top end. The job here is not power; it is castability. By demanding only generic mana, it drops into any color combination and any artifact-themed shell, which is the entire reason a vanilla construct at this cost ever earned ink. The 6/4 split is the only real decision on the card, and it points one direction: four toughness rules out a defensive role, while six power means it trades up or races, a deliberately offensive stat line for a creature far too expensive to function as a tempo play. The construct exists to give a synergy-light deck a top-end beater that costs nothing in deckbuilding flexibility, a body to deploy when the curve runs out of cheaper plays. Beyond that there is nothing to unpack: no keyword, no trigger, no activated ability, just a large artifact body priced well above what raw stats have ever commanded.
