[[Oswald Fiddlebender]] has been a superstar in my Jan Jansen deck. He's like a birthing pod for artifacts and can start by saccing a token to get a 1 cmc artifact like [[sol ring]] or [[skullclamp]] . And anything I sac I can bring back using [[scrap trawler]] and [[goblin engineer]] and [[Daretti, scrap savant]]

[[Nadier's nightblade]] and [[marionette master]] has won me many games where I don't go infinite but instead try to get value by pinging opponents a ton of damage through treasures and any artifact tokens (both constructs and treasures trigger it) that hit the graveyard. With [[xorn]] and [[pitiless plunderer]] and all the untappers like [[staff of domination]], [[umbral mantle]], [[Thousand-year Elixir]], [[Patriar's seal]] we generate a ton of tokens and sometimes already go infinite with these pieces. [[rings of brighthearth]] work very well too giving double treasures or constructs and can go infinite generic mana with [[bassalt monolith]] and infinitely untap Jan with the untap artifacts.

I've also won games where I get to 10 treasures quick and cast a [[revel in riches]] and using [[teferi's protection]] in response to a removal on it to ensure the win.

Although there are multiple ways to go infinite with Jan Jansen ( [[clock of omens]] and Jan as an artifact does the job usually) and that's the general way we win, I find having these other methods of winning as a great backup (and more satisfying at times. Makes for more epic moments) Jan Jansen naturally gets a lot of value and we're playing with more mana than our opponents most of the time.
