Enatu Golem

Six mana for a 3/5 that hands you four life on its way to the graveyard is the rate of an era when colorless filler had to be wide enough that any deck could run it. The body fights ground stalls competently and the death trigger softens the loss, but neither half is trying to win a game; together they describe a card built to fill out a curve and a creature count rather than to do a job. The death-triggered lifegain points at the one context where it earns its slot: a deck that intends to sacrifice or trade away its own artifacts and would rather bank the four life than let the chump block go to waste. Absent that, this is the kind of colorless creature that exists so a curve has a body at the top end and a five-color deck has something to splash-free, not because the design has a question it answers.
