Aspiring Champion + Blightsteel Colossus + Sylvan Tutor + Conspiracy

Aspiring Champion

Blightsteel Colossus

Sylvan Tutor

Conspiracy

How it works

1. Cast Sylvan Tutor by paying , searching your library for Blightsteel Colossus and putting it on top of your library.
2. Deal combat damage to an opponent using Aspiring Champion.
3. Aspiring Champion triggers, causing you to sacrifice it, then reveal Blightsteel Colossus from the top of your library and put it onto the battlefield as a Demon due to Conspiracy, then causing Blightsteel Colossus to give each opponent eleven poison counters.
4. Each opponent loses the game as a state-based action due to having ten or more poison counters.

Sylvan Tutor sets up the top of your library precisely, letting you search for Blightsteel Colossus so it waits right where you need it. Meanwhile, Conspiracy reshapes the creature types across the board, ensuring that when Asp aspiring Champion connects in combat and triggers its Ruinous Ascension sacrifice clause, any creature you cheat into play counts as a Demon. Because Conspiracy transforms Blightsteel Colossus into a Demon even while it is a card you own not on the battlefield, the freshly revealed titan instantly triggers its newfound type's damage-equal-to-its-power clause—delivering a lethal dose of infect damage straight to your opponents.
