Combotastic Sidisi Deck:

---

The Deck tries to win either through Laboratory Maniac, a horde of pumped Zombie Tokens or Jarad flinging a giant Monster at the enemies (or Sheperd of Rot if you're cheeky).

Some synergies to get you there (by all means not comprehensive - while playing this deck there are soo many lines to choose from, these are the most common ones):

Looters+ Dredgers+ Intruder Alarm for huge amounts of self mill and zombies (but not necessarily infinite)

Discard Outlets+ Dredgers+ The Gitrog Monster same as above

Untappers+ Mesmeric Orb again as above, this is actually infinite mill

Gravespawn Sovereign + Intruder Alarm + 4 other Zombies (infinite reanimation, especially good with sacrifice and discard outlets )

Filth + Urborg (makes all your creatures basically unblockable)

Cephalid Illusionist + Lightning Greaves (selfmill again)

Necrotic Ooze + Phyrexian Devourer + Triskelion (pings your opponents for damage equal to the total cmc of your remaining library (while exiling it in the process). Note that a) Devourer and Triskellion need to be in your graveyard and b) Devourer gets, other than stated on its card, X +1/+1 counters instead of an +X/+X counter.)

---

To get you there, this deck runs a ton of mana dorks for a turn 3 Sidisi, as well as a bunch of looters (Magus of the Bazaar is nuts). Traverse the Ulvenwald quickly becomes a 1 Mana Demonic Tutor. The Transmute creatures get you the combo pieces of your choice (Life from the Loam, Mesmeric Orb, Cryptolith Rite, Intruder Alarm, LabMan).

I tried to keep the creature count very high for obvious reasons. I'm not a fan of playing noncreature spells in this deck, if there's a suitable or semi-suitable creature replacement (think Counterspell -> Mystic Snake)

---

Some further observations:

Villainous Wealth is gas. So is Praetor's Counsel (If you ever get to cast it).

Life from the Loam makes the deck tick. Try to get it very early (ideally you dredge it the turn after sidisi came down).

Intruder Alarm combo's with half the creatures in this deck.

Discard Outlets are very important.

Dread Return wins you the game when it's flashed back.

This deck can also make good use of sac outlets from time to time.

---

Cards that belong in the deck, but are in my cube instead:

Basalt Monolith

Merfolk Looter

1-Mana Dorks

Reclamation Sage

Craterhoof Behemoth

Gaea's Cradle

---

There's a bunch of other possible combos you can run (Full-on basic land-less Hermit Druids, Mike+Trike and other Ooze Shenanigans, ...)

other great additions to the deck:

psychatog (discard outlet + gets HUGE for jarad)

lord of extinction (also for jarad)

cryptbreaker

living death

zombie lords if you like

aphetto alchemist

altar of dementia and embalmer's tools (I really need to get my hands on some of these)

entomb

---

cards I'd cut from my version:

compulsive research

corpse augur

and maybe 1-2 lands, up to preference

---

disregard the land base
