Insta win

[AgrusKos]

{Labratory maniac} and {Leveler}. So leveler has its uses in non torpor orb decks

[BlackJester]

Id suggest having instant-speed draw as well in case they {Doom Blade} your maniac.

[Maximo]

Add a {thought scour}

[Gorzo]

Not technically "insta" since your opponent has from the time leveler is put on the stack until your next draw to {murder} your lab maniac and turn your win into a lose with no way out.
But it is a good combo nonetheless, if they don't have any destroy or counter spells in hand, your opponent is in trouble.

You could wait til turn 5 to play leveler then {ponder} or some other 1 drop draw a card.
