Darksteel Splicer

The Splicer template built its whole appeal on a scaling body it never printed on itself: the mechanic gives you Golems and hands them a keyword, and the artificer stays a fragile 1/1 while its tokens carry the game. This one takes that framework and rewires two things about it. The keyword handed to the Golems is indestructible rather than the +1/+1 the original Splicers granted, so the tokens are not bigger, they are unkillable by damage and destruction alike. And the token count keys off your opponent count, an explicitly multiplayer-scaling design that produces a single 3/3 in a duel and a wall of them at a full table. The trigger is broad, too: it fires on any nontoken Phyrexian entering, not just the artificer itself, so the card rewards a Phyrexian-typed board rather than a single reusable engine piece. That widening is the point. Where the classic Splicer wanted you to chain more Splicers for stacking anthems, this asks you to flood the battlefield with Phyrexians of any kind, each one a fresh batch of indestructible Golems whose count grows with the number of players trying to stop you.
