Nim Grotesque

The 3/6 body is the tell: this was built as a wall that grows teeth. The defensive toughness is what makes the +1/+0 per artifact a credible threat rather than a liability, because the card can hold the ground while its bonus climbs, then turn and swing once the board is wide enough. The design sits at the seam between two creature identities: it blocks like a control piece and attacks like a beater, with the slope of that transformation set entirely by the density of artifacts on your side. That makes it a payoff, not an engine; it does nothing to find artifacts, only to cash them in once they arrive. The seven mana is the honest part of the math: by the time you can pay it, an artifact deck should already have the permanents down to make the static bonus matter, so the rate reads as steep but lands near the point where the deck has the fuel to justify it. Strip away the artifact count and you are left with a vanilla 3/6, and that floor is the quiet discipline in the design: a deck that fails to deliver the artifacts holds an oversized blocker rather than a dead card. The whole thing rises or falls on board state, the conditional power a creature this large and this expensive ought to be asking for in the first place.
