Galactus

Galactus is a colorless/artifact-heavy Commander ramp deck with a go-wide Constructs/robots subtheme. Its main plan is to accelerate mana with rocks and mana creatures, then deploy efficient artifact bodies and big finishers like Metalwork Colossus, Meteor Golem, and likely its commander-supported payoff.

Key synergies come from cost reduction and artifact density with cards like Etherium Sculptor, Foundry Inspector, and Starnheim Courser, plus anthem/support pieces such as Chief of the Foundry and Steel Overseer to grow a board of small artifact creatures and tokens. The deck also gets value from artifact recursion and fodder through cards like Junk Diver, Workshop Assistant, Servo Schematic, and Mycosynth Wellspring.

It typically wins by overwhelming the board with buffed artifact creatures, then pushing damage through with cards like Crashing Drawbridge for haste or Rogue’s Passage to force through a large threat.
