Artifacts you control are Clues in addition to their other types and have ", Sacrifice this artifact: Draw a card."
Whenever you sacrifice a Clue, target creature can't be blocked this turn.
Senator Peacock turns every artifact you control into a card-drawing Clue, so you build a wide artifact base, refuel your hand, and convert those sacrifices into repeated unblockable triggers. Early turns you ramp with mana rocks and cheap artifacts, then deploy a threat (often Peacock-fueled Voltron or a single big evasive creature) and crack Clues to push lethal connected damage. The deck plays like an artifact-storm value engine that suddenly weaponizes its card advantage into unblockable beats.
Relentless card advantage—every artifact you cast becomes a draw engine even without specific synergies
Reliable, repeatable evasion makes any single creature a guaranteed lethal threat
Mono-blue gives access to counterspells, protection, and the best card draw in the format
Plays well with artifact ramp you'd run anyway, so the engine costs little deck space
Mono-blue lacks efficient removal and struggles against resolved problematic permanents
Peacock himself is fragile and the unblockable trigger requires him on the battlefield
The sacrifice cost makes drawing/evasion mana-hungry without cost reducers
Vulnerable to artifact wipes and graveyard hate that punish the sacrifice plan
Telegraphs the alpha strike—savvy tables can hold up interaction
