Aristocrats Infinite Combo
Get all three of these guys out and win the game:
Zulaport Cutthroat
Eldrazi Displacer
Brood Monitor
Sac the three Eldrazi Scions that came into play from Brood Monitor for mana which triggers Zulaport Cutthroat's ability doing 3 damage to your opponent and you gain 3 life.
Use the mana to activate Eldrazi Displacer's ability and exile Brood Monitor.
Brood Monitor comes back into play tapped but with three new Eldrazi Scion tokens. Rinse and repeat.
Tutors
A tutor for going out and getting the pieces needed for the infinite combo. The beauty is if you at least have him and Eldrazi Displacer out, you could bounce him and tutor twice. He's also a death trigger for Zulaport Cutthroat or Catacomb Sifter, life or scry.
An eldrazi scion factory and you can sac it to tutor for Brood Monitor or Eldrazi Displacer.
Maybe not technically a tutor since I can't grab whatever I want, but it helps me dig through my deck and at least hit a creature most often for the measly cost of an Eldrazi Scion.
Card Draw/Scry
Bounce her with Eldrazi Displacer for a three mana card draw
I'm going to be killing creatures and this sifty (pun) guy lets me scry my way to the cards I need.
Mana and Land
Westvale Abbey
Can be devastating back up plan if this deck draws right. If I'm not able to draw Eldrazi Displacer but I have Zulaport Cutthroat and enough scions, sac targets, and mana out, it's huge.
Minimum 5 damage right off the bat with Zulaport Cutthroat, I get a 5 life, possibly scry my way to a Eldrazi Displacer if Catacomb Sifter is out, and then a scary 9/7 Demon with Flying, Haste, Lifelink, and Indestructible.
This is to ensure I can summon Eldrazi Displacer or Brood Monitor. It's fast mana for a bit of pain but life generally doesn't matter in this deck if it plays right.
Other than fixing my curve this card can get ridiculous in the right circumstances.
Simply put, tap a scion for ANY color you want, then sac it to get a colorless and you're triggering Zulaport Cutthroat.
Suggestions & Upvotes please
Any suggestions are greatly appreciated as I know this deck lost a lot of power in standard when Siege Rhino rotated out, so I'm looking for ideas.
I especially need help with the sideboard as I generally struggle putting together a good sideboard and it can sometimes bite me in the butt.
Thanks for checking out my deck, if you like it please upvote it.
