The retooling of your entire artifact base into a draw engine is the obvious line, but the second ability is where the design actually lives. Turning every artifact you control into a Clue with a built-in "draw a card" clause is card advantage; stapling an unblockable trigger to each Clue sacrifice is a wholly separate axis, and it reframes those artifacts as evasion enablers rather than a value pile. A Treasure token you crack for mana now also pushes a creature through; a mana rock you never intended to sacrifice becomes a threat of one. The tension is between hoarding those artifacts for the card draw and spending them to close a game, and this legendary Advisor forces you to price every crack against both outcomes at once. Note that the unblockable effect fires on any Clue sacrifice, not only the ones this card grants, so a deck already investigating stacks the triggers naturally. The 3/4 body is deliberately mild: at five mana this is a build-around, not a beater, and it wants to sit behind a board of artifacts doing double duty. What it represents is a bridge between two archetypes that rarely overlap: the artifact-value shell that wins by grinding, and the tempo shell that wins by connecting. Peacock asks a single question of both: what if the resource you were already spending also decided combat?
