Hey! I really like the look of this deck, looks like a blast. :) I can't really suggest much to improve it, looks pretty good already. Jeskai Sage might have potential for pumps and card draw, as would Ninja of the Deep Hours. Looks like you have plenty of evasion, might be interesting to see if Stealer of Secrets/Scroll Thief or Last Thoughts could work for card draw, especially in conjunction with with Assault Strobe to draw 2 cards? And I personally prefer Peek over Thought Scour.

A sweet looking deck though, gonna have to try it some time!

When I saw the name of this deck, I thought it was some sort of mono black energy because of Live Fast and Die Young. I do love Izzet aggro tho

Snivy__, thanks for the comment. The deck name comes from its gameplay: either you win fast on turn 3 or lose fast when you don't draw a creature, lol.

Hey! Love your deck series! +1!

Would you consider replacing Titan's Strength with 4x Renegade Tactics? it produces an effect similar to Slip Through Space ensuring your dudes get through, and it's a cantrip, rather than "just" a scry.

Also, Preordain is typically better than Serum Visions and roughly the same price. =)

sorry, didn't realize you said Pauper/Modern until too late. you can still use Renegade Tactics though.
