The focus of this deck is to threaten the opponents creatures, attack with them and then sacrifice them to the different spells with additional sacrifice cost. Its also possible to just beat down with all the small guys we have.

Disclaimer: this deck is just a rough concept of what it could be and is not really tested at all. Suggestions are welcome!

Collateral Damage : A Lightning Bolt with a big drawback which doesnt seem too bad if we sac an opponents guy that we got with Yasova Dragonclaw or Jeering Instigator . Also, sacrificing a Humble Defector to it in response to its activated ability prevents him from joining the enemy team.

Elvish Mystic: The things we want to do in this deck are kind of mana intensive, so having a little bit of ramp seems fitting. he also gives an extra mana from Xenagos, the Reveler and is potential food for Collateral Damage .

Flamerush Rider: Just a cool card that nobody seems to really like. If he dashes out and causes the opponent to take way more damage than he thought he would, he seems okay. The token he produces can also be sacrificed to Collateral Damage .

Humble Defector: A 2/1 for 2 mana isn't the best but also not the worst. His ability can be abused in some ways in this deck. The previosly mentioned play with Collateral Damage is possible as well as using his ability pre combat and then getting him back with Yasova Dragonclaw or Jeering Instigator to use him again.

Jeering Instigator : Act of Treason on a stick. Synergizes with the spells in the deck, and can just be a 2/1 for 2 that swings in if he does not have a target or the mana is short.

Temur Sabertooth: This guy is just a solid threat that can survive a lot of things. He can also bounce a stolen creature if we dont have anything to sac it to. Bounces a Humble Defector in response to his activation.

Rattleclaw Mystic: More Ramp and another 2/1 body.

Xenagos, the Reveler: Even more ramp and also pressure when he spits out his Satyrs. Just solid and has to be dealt with.

Yasova Dragonclaw : She can be ridiculous with some of the card in this deck. Stealing a guy every turn in conjunction with Temur Sabertooth can get rid of an enemy board over time if you have the mana and all the previously described combinations are possible with her ability.

(Xenagos, God of Revels: He seems kind of slow and the devotion will almost never be high enough to get him alive, but his ability is very useful. He can pump Yasova Dragonclaw to let her steal bigger things like a Siege Rhino.

Life's Legacy: Can draw some cards while getting rid of a stolen creature.)
