Golem Artisan

A one-card anthem for a metal board, and the design splits the work cleanly into two halves: a repeatable pump and a repeatable evasion-or-tempo grant, both priced at two mana so neither dominates the other. Neither activation touches itself in a useful way (a 3/3 that has to pay to grow or fly is a slow clock alone), which is the tell that this was built as a payoff for going wide on artifacts rather than as a standalone threat. What makes it sturdier than a flat lord-style enabler is that the granted abilities are modal: flying to push damage through a clogged ground, trample to make an oversized attacker punch past chump blockers, haste to give a freshly cast artifact creature immediate reach. Each costs the same, so the texture of any given turn comes from which keyword the board actually needs, not from a fixed bonus. The pump and the keyword grant stack on a single target, turning one creature into a flying, trampling finisher when the mana is there to feed both. It contributes nothing the moment the rest of the artifact creatures leave the table, and everything when they stay: an anvil for a swarm of constructs, golems, and servos, rewarding the density of the board rather than supplying it.
