$21 (not counting lands) Sidisi Ad Nauseam Combo.
Strategy
Turns 1-4: play
Swamps
.
Turn 5: Play a
Swamp
, then play
Sidisi
, exploiting herself to get
Ad Nauseam
. Then discard a
Swamp
at the end of the turn because you have 8 cards in your hand.
Turn 6: Do not play a land yet. Pray to Emrakul that your opponents don't have a counterspell, then play
Ad Nauseam
, drawing your entire deck, taking, at most, 5 damage. Then play
Glacial Chasm
as your land for the turn, sacrificing a
Swamp
. Play
Lotus Petal
, then crack it for to cast
Dark Ritual
, floating . Use one mana to play
Elixir of Immortality
as a contingency plan. Then cast
Sickening Dreams
, discarding your entire hand except three
Swamps
, dealing 84 damage to each opponent, with
Glacial Chasm
preventing the damage that would normally be dealt to you, thus probably winning you the game.
If you didn't win on turn 6
If you successfully resolved Ad Nauseam: If you have 21 or more life, keep
Glacial Chasm
, otherwise let it die. Then crack
Elixir of Immortality
on your turn 7 upkeep (after the
Glacial Chasm
trigger) to reset the combo and avoid decking out. Then on turn 9 play
Sidisi
to get
Ad Nauseam
and start the combo again on turn 10.
If you did not resolve Ad Nauseam: Play
Sidisi
on turn 7 to get
Codex Shredder
. On turn 8 play
Codex Shredder
and sac it to get
Ad Nauseam
back. On turn 9, start the combo again.
If you like this deck, but wish it was actually good
You can try Nakhla's excellent primer, Sidisi's Reign Of Filth, which is blazing fast cEDH combo deck capable of winning consistently by turn 3, with turn 2 wins being common. And, unlike this deck, it can actually win against the same person more than once.
If you don't want to drop $2k on Nakhla's list you can try my $130 Sidisi deck, Sidisi Ad Nauseam Fishbowl. It is not nearly as fast or resilient as Nakhla's list, but it does follow a similar game plan, winning by storming off with
Aetherflux Reservoir
, or by casting a giant
Exsanguinate
.
