Belcher FamilyMikaeus, the Unhallowed Buy + Ashnod's Altar Buy + Plague Belcher Buy
This has not yet been posted, so I'm dropping it here. Belcher targets itself with the -1/-1 counters, negating the undying +1/+1 counter. Sac outlet of choice, Altar was just easiest to think of. Inf ETBs and death triggers (and mana, in this case).
Singular ArtisansEye of Singularity Buy + Faerie Artisans Buy
Locks your opponents down... Their creature dies, you will get the temporary copy, if they try casting a creature.
Deus Vult (f./Thassa's Oracle from THB)Demonic Consultation Buy + Jace, Vryn's Prodigy Buy
JVP is a stand-in for Thassa's Oracle (THB, Rare).
Play Thassa's Oracle.
Then, after it resolves, in response to
the ETB trigger, play DC and name a card
that's not played in your deck.
Produces an instant win via T.O.,
from any boardstate.
Servants to Composted Thinking.Painter's Servant Buy + Compost Buy + Psychic Corrosion Buy
1. Play all three, with Painter's Servant naming Black.
2. Draw a card however you choose.
Short of someone having an
Eldrazi Titan in their deck,
this will deck the table.
And you will have your deck in hand.
Oldest Trick In The BookChaoslace Buy + Blue Elemental Blast Buy
Chaoslace your opponent's Nightmare or Shivan Dragon or Force of Nature or Mahamoti Djinn, then Blue Elemental Blast it!! Can even counter spells or whatever!
InstaPitiless Plunderer Buy + March of the Machines Buy
Transform your Treasures into 0/0 creatures and create and infinite loop.
Add Reckless Fireweaver Buy to infinite damage
Chieftain of the War-TideStonehoof Chieftain Buy + Nacatl War-Pride Buy + Coat of Arms Buy
Have all three in play. Enter combat, attack with the creatures. If your opponent has 0 creatures, you hit for 13 damage. If they have 2 creatures, you are swinging for 29 with 17 of it being trample and the nontoken War-Pride is indestructible. It gets pretty absurd the more creatures your opponent has.
Potent Citadel ReservoirBolas's Citadel Buy + Aetherflux Reservoir Buy + Necropotence Buy
Bolas's Citadel is already really easy to abuse with the Reservoir, but you usually stop after hitting a land. With Necropotence, you can exile that land for only 1 life and continue chaining spells.
If you don't win with casting your whole deck, you will almost certainly hit 50 life for the Reservoir at least once.
Begin the Ritual!Shadowborn Apostle Buy + Razaketh, the Foulblooded Buy + Bloodbond March Buy
There was another combo here that used the Apostles only once per turn.
1. Activate Apostles. Get Razaketh.
2. Sac a creature (like another Apostle) to tutor for an Apostle.
3. Cast Apostle. Get all in grave to field.
