Welder Automaton

A 2/1 for two is perfectly ordinary aggressive curve-filler; the activated ability carries whatever design interest the card has, priced deliberately steep so it never becomes the plan. Spending to ping each opponent for one is a poor rate as anything resembling reach, which is exactly the point: this is a colorless attacker first and a slow inevitability engine a distant second, a body that pivots into a mana sink only once the game has stalled and the red mana sits idle. The construction belongs to a long line of artifact creatures that want to be played for their stats but carry a repeatable activation as a floor against flooding, giving an aggressive deck something to do with its eleventh land. Note that the ability hits each opponent rather than any target, so it does nothing to clear blockers or stabilize a board; it only chips at life totals, which makes it a closer in multiplayer arithmetic and a near-dead button in duels, where four mana for a single point loses you the race it was meant to win. The honest read is a common-rarity beater whose ceiling is reaching a stalled opponent for the last few points, nothing more.
