Commander deckUW
Rex, Cyber-Hound
Fill graveyards through self-mill and looting, then use Rex to exile key creatures with brain counters to steal their activated abilities. Combine mana generation, untap effects, protection, and draw abilities on Rex while building an evasive artifact board state.
Asked for“Crie um deck Commander de exatamente 100 cartas com Rex, Cyber-Hound como comandante. Tema principal: Robots, Artifact Creatures e tecnologia. Budget máximo de US$100, ignorando comandante e terrenos básicos. Quero Bracket 2 alto, nível precon moderno forte: consistente, sinérgico e justo. O foco deve ser Rex acumular muitas habilidades ativadas úteis de criaturas exiladas. Priorize criaturas W/U ou incolores com habilidades ativadas fortes e variadas: proteção, evasão, draw, remoção, geração de mana, untap, buffs e utilidade. Inclua boas formas de gerar Energy, fazer Rex causar dano de combate, mill incidental para abastecer cemitérios, proteção, ramp, draw e interação. Evite criaturas escolhidas apenas por serem artefatos/Robots se não ajudarem o plano. Sem combos infinitos, stax, Game Changers ou muitos tutores. O deck deve funcionar sem Rex, mas ficar progressivamente mais versátil conforme ele acumula habilidades.”
Deck anatomy
What this list actually runs on: how cheaply it casts things, and whether it has enough ramp, card draw and interaction to keep up at the table. Each block is one card — hover for its name.

The working parts
Counted from Scryfall’s community card tags, not from the builder’s own labels. A card that does two jobs counts twice, so these add up to more than the deck. The hatched band is a common rule of thumb, not a law — combo decks run leaner, battlecruiser decks heavier.
