I designed the concept for this deck way too late at night with a friend of mine. Instead of just playing a boring Laboratory Maniac deck and drawing the deck out, what if everyone got a Laboratory Maniac and everyone got a win. So this deck is made to mill everyone to a few cards left in their decks. At which point Tempt with Reflections allows anybody who wants a Laboratory Maniac to get a copy of him. the rest of the mana that turn gets used on Jace's Archivist or something to make everyone mill themselves. Because each person will have drawn themselves out before the next state-based action check thing occurs, each person will have a Laboratory Maniac win-con happen simultaneously. Effectively allowing anybody who opted in to Tempt with Reflections to end the game with a win

Final Turn

Already on field: maybe Jace's Archivist, preferably Gauntlet of Power

(optional) cast High Tide to have enough mana

Cast Laboratory Maniac, then cast Mirrorweave or Tempt with Reflections

Activate Jace's Archivist or play Minds Aglow or Prosperity with the extra mana from High Tide and/or Gauntlet of Power. Assuming that you paid enough mana to make everyone draw out their deck, simul-win should be achieved.

This deck can take at least 10 turns to get to the win-con, but its worth it in my opinion
