Forensic Gadgeteer triggers, creating a Clue token.
Activate Urza's first ability by tapping the Clue, adding .
Activate Sensei's Divining Top's second ability by tapping it, causing you to draw a card and put Sensei's Divining Top from the battlefield on top of your library.
Activate the Clue by paying 1 and sacrificing it, causing you to draw Sensei's Divining Top from the top of your library.
Repeat.
This clever engine loops Sensei's Divining Top for endless card draw, fueled by Urza, Lord High Artificer turning your artifacts into mana sources. Forensic Gadgeteer plays a pivotal double role here, dropping the activation cost of your Clues while constantly generating fresh ones whenever you cast your artifacts. Meanwhile, Stenn, Paranoid Partisan sits quietly on the battlefield reducing your artifact spell costs—or can even be blinked away if you need to reconfigure your choices. Together, they create a self-sustaining loop that spins through your deck, racks up a massive storm count, and draws you into whatever game-winning finisher you need.
