In the spirit of Yasova, this was mostly stolen from the awesome "stop hitting yourself" net deck: http://tappedout.net/mtg-decks/stophittingyourself/

HOW THIS WORKS: The plan here is to steal everyones best creatures, via commander, noncreature spells, activated abilitys, and/or creature spells.
To make creature spells more effective i put lots of copy spells, like Clone to copy my creature stealing creatures, like Zealous Conscripts. If i dont have a sac outlet ill just copy your really good creature such as eldrazi's or whatever. After i take your creatures til the end of the turn, I do what i want with them. I can hit you with them, then tap Bazaar Trader to keep them, or i can sac them to Birthing Pod or Jalira, Master Polymorphist to get another creature that could possibly steal another creature that i would just do what i want with.. I like being the bully.

STEALING STUFF:
CREATURES FOR STEALING: Willbreaker, Conquering Manticore, Dominus of Fealty, Keiga, the Tide Star , Molten Primordial, Yasova Dragonclaw, and Zealous Conscripts. Prophet is banned but I'll leave this here anyway... Feldon of the Third Path + Keiga, the Tide Star + Prophet of Kruphix to steal a creature every turn... Yasova Dragonclaw + Willbreaker steals a creature every combat in your turn.
SORCERY SPELLS FOR STEALING: Insurrection, Mass Mutiny , Mob Rule. for instant speed Domineering Will . The only artifact for stealing, Helm of Possession. The planeswalker for stealing, Sarkhan Vol. Ashnod's Altar + Insurrection can also be used as a board wipe.
MAKING STEALING MORE EFFECTIVE: Bazaar Trader keeps what i steal for good, so does Conjurer's Closet, and Deadeye Navigator... Cast Clone, Dack's Duplicate, Phyrexian Metamorph, Progenitor Mimic, or Stolen Identity and target any one of my own "creature stealing creatures" to steal more creatures... Use Mimic Vat and target a "creature stealing creature" to steal over and over again. Feldon of the Third Path will do the same thing... Jalira, Master Polymorphist is perfect for after stealing a creature, sac the creature to her and reveal the top cards til hopefully you score for another one that steals creatures too. Birthing Pod does this too in a similar way... Dominus of Fealty happens at the beginning of upkeep, so does Followed Footsteps ... Cast Deadeye Navigator and pair him up with any of the good "creature stealing creatures" like Molten Primordial and flicker him with Deadeye Navigator's ability... Helm of Possession is real cool. Steal a creature, sac it to Helm of Possession and steal another creature for as long as Helm of Possession remains tapped... Cauldron of Souls is a cool way to sac your own creatures for the enter the battlefield effect to happen again like Zealous Conscripts. Splinter Twin is good on any "creature stealing creature", but is infinite with Zealous Conscripts. The Splinter Twin + Zealous Conscripts .

SAC OUTLETS AND OTHER SIMILAR STUFF: Bloodshot Cyclops , Greater Gargadon, Jalira, Master Polymorphist, Demonmail Hauberk , Helm of Possession, Evolutionary Leap, Thermopod , Ooze Garden , Perilous Forays, Greater Good, greater good is really great when you have Phytotitan already in play, draw 7 discard 3 every turn. Ashnod's Altar, is usually what you'll use you Academy Ruins for, and Birthing Pod, this card is perfect cause most time the creature you sac will land you the one you need. THE OTHER STUFF: Bazaar Trader, Conjurer's Closet, and Safe Haven .

KEY CARDS: Birthing Pod, Helm of Possession, Phyrexian Metamorph, and Acidic Slime. Acidic Slime plays a Huge role in this deck. It works very well with Mimic Vat, and Feldon of the Third Path if it has died, but if it has not then any copy spell works great too. Other things that work great are Deadeye Navigator, and Conjurer's Closet. "Thats making the best use of an uncommon card". So if you're up against someone, they better exile Acidic Slime rather than destroying it, because my graveyard gets just as much use as what's in play.
