Piles

I'm teaching myself how to build good doomsday piles in theory, working backwards.

Let's start my building efficient pass the turn (PTT) piles that win the game with the fewest resources in the face of no resistance.

Here are a few of the most famous win conditions.

;Thassa's Oracle; ;Laboratory Maniac;

Simplest, Perfect Pile

PTT + 8 life + {U}{U}

;Street Wraith#(PTT + 2 life) ;Street Wraith#(2 life) ;Street Wraith#(2 life) ;Street Wraith#(2 life) ;Thassa's Oracle#Comment: ({U}{U}). Yay!;

Simplest, Imperfect Pile

PTT + 4 life + {U}{U}

;Street Wraith#(PTT + 2 life) ;Street Wraith#(2 life) ;Thassa's Oracle#Comment: ({U}{U}). Yay!; ;Card Back; ;Card Back;

Vintage Pile

PTT + {U}

;Ancestral Recall#(PTT + {U}) (Banned in Legacy!) ;Black Lotus#+{U}{U}{U} ;Thassa's Oracle#({U}{U}), {U} extra. ;Card Back; ;Card Back;

PTT + Land

;Ancestral Recall#(PTT + {U}) (Banned in Legacy!) ;Lotus Petal#+{U} ;Lotus Petal#+{U} ;Edge of Autumn#(Land) ;Thassa's Oracle#({U}{U})

PTT + {U}

;Ancestral Recall#(PTT + {U}) (Banned in Legacy!) ;Black Lotus#+{U}{U}{U}(Banned in Legacy!) ;Thassa's Oracle#({U}{U}) ;Consider#({U}), Draw final card. ;Card Back;

PTT + {U}

;Ancestral Recall#(PTT + {U}) (Banned in Legacy!) ;Black Lotus#+{B}{B}{B}(Banned in Legacy!) ;Entomb#({B}), Put Oracle in Graveyard. ;Shallow Grave#({1}{B}) ;Thassa's Oracle;

PTT + {U}

;Ancestral Recall#(PTT + {U}) (Banned in Legacy!) ;Black Lotus#+{B}{B}{B}(Banned in Legacy!) ;Entomb#({B}), Put Oracle in Graveyard. ;Unearth#({B}) # {B} extra. ;Thassa's Oracle;

Legacy Piles

PTT + {U} + 3 life. Fewest Mana possible?

;Consider#({U}), Put Deep Analysis into Graveyard. ;Deep Analysis#({1}{U}, 3 life.) ;Lion's Eye Diamond#+{U}{U}{U}. Pays for DA. ;Lotus Petal#+{U} ;Thassa's Oracle#({U}{U});

PTT + {U}{U}. No life required.

;Ideas Unbound; ;Lion's Eye Diamond; ;Consider; ;Card Back; ;Thassa's Oracle;

PTT + {1}{U} + ≤ 1 card in hand.

;Quantum Riddler; ;Lotus Petal; ;Consider; ;Lotus Petal; ;Thassa's Oracle;

PTT + Fetchland + ≥ 1 card in hand.

;Brainstorm# Draw for turn. ;Island# Fetch with fetchland +{U}.
Use to cast Brainstorm. -{U} ;Consider#Draw with brainstorm. Cast under LED, discard card over TO.; ;Lion's Eye Diamond#Draw with brainstorm. Activate over Consider. ;Thassa's Oracle#Draw with brainstorm.
Put back card + this post brainstorm. Draw with Consider.;
