Stuffy Doll and Pariah is the central theme, the rest of the deck is either here to set it up or add to the effect in some way. This deck was more a conceptual exercize on getting a deck together that could support this combo, its not really affordable OR legal.
Angel's Trumpet
Puts the opponent in a difficult position once Stuffy is up and running. Attack me and take damage, or don't and take damage.
Fabricate
A lot of this is artifacr based so having an artifact tutor is nice. Even can tutor for the Stuffy.
Guilty Conscience
One of the wincons. Put this on Stuffy Doll and it infinite loops to kill its target.
Mana Leak
Helps, thwart any solutions your opponent may come up with.
Norn's Annex
Pairs well with Angel's Trumpet. If they attack, there's a price.
Pariah
Transfers any damage dealt to you to the Stuffy.
Pariah's Sheild
An alternative for Pariah that you can tutor with Fabricate
Perimeter Captian
A good early game play to have some defense.
Preordain
Little card draw
Renowned Weaponsmith
Helps you cast Artifacts for cheap.
Spirit Link
Might as well be gaining life from Stuffy too right? Especially if you have multiple opponents to deal with.
Stuffy Doll
Other part of the main combo with Pariah
Sunbond
Can make your Stuffy able to actually attack and defend for real, if the lockdown this deck causes ends up lasting too long.
Tarnished Citadel
Deal damage to yourself, which gets transfered to your opponent. Also get mana, too.
Transmute Artifact
Replace a Stuffy if you need to switch targets or if one of them gets nullified.
