Whenever you cast a noncreature spell, create a Clue token. (It's an artifact with ", Sacrifice this token: Draw a card.")
: Until end of turn, target artifact token you control becomes a 3/1 Construct artifact creature with flying.
Cast cheap noncreature spells to flood the board with Clue tokens, then use The Mechanist's tap ability to animate those Clues (and other artifact tokens) into 3/1 flying Constructs that swing for surprise damage. You build a wide artifact-token board while drawing cards off Clues, eventually overwhelming with flyers or going off with token-doublers and untappers.
Every instant, sorcery, artifact, and enchantment you cast nets a Clue, giving relentless card advantage in mono-blue
Turns dead artifact tokens into evasive 3/1 flyers for repeatable, flexible damage
Mono-blue gives access to deep counterspell and protection suites to defend the engine
Synergizes beautifully with token doublers, untap effects, and artifact-matters payoffs
The animation only hits one token per turn without untappers, making damage slow
