You've tested the the deck ehh?

Post your results. What is your win/loss ratio so far? What kinds of decks are you bad against? Is it enough control for aggressive decks? How frequent is your combo going off? How useful is Elixir?

We wanna know everything!

Three-colored version of a Simic bounce deck (repost from there) :

Here's Da Combo ! :
Lands (24):
8x Island
6x Forest
2x Swamp
4x Simic Guildgate
2x Golgari Guildgate
2x Dimir Guildgate

Creatures (15):
3x Elvish Visionary
2x Quickling
3x Archaeomancer
2x Saruli Gatekeepers
2x Species Gorger
2x Rune-Scarred Demon

Spells (17):
4x Fog
2x Treasured Find
4x Voyage's End
4x Think Twice
3x Dissolve
1x Time Warp

Artifacts (4):
1x Elixir of Immortality
3x Darksteel Ingot

The plan is easy enough :
- Stall long enough by abusing etb/bounce/fog effects to draw/tutor into combo then make fun of your enemy by playing infinite turns.

Well, they are basically almost identical.
But since the deck is mostly blue-oriented, I thought that using colorless mana would be more consistent than requiring green mana.
Plus, the ingot is more flexible than lands color-wise.

That, and I honestly think there are way better targets for Archaeomancer than Cultivate.

Counterspells are mandatory here, since you're not really packing a lot of removal playing
Fogs. Yeah. Not sold on them either, I have to admit.

I'm actually pondering removing them altogether, and redo the deck to include Gravedigger and Flesh to Dust or Ulcerate

Something like that :
Here's Da Combo ! :
Lands (24):
7x Island
5x Forest
3x Swamp
3x Simic Guildgate
3x Golgari Guildgate
3x Dimir Guildgate

Creatures (16):
3x Elvish Visionary
3x Quickling
2x Archaeomancer
2x Saruli Gatekeepers
2x Gravedigger
2x Species Gorger
2x Rune-Scarred Demon

Spells (16):
2x Ulcerate
4x Voyage's End
4x Think Twice
3x Dissolve
1x Time Warp
2x Flesh to Dust

Artifacts (4):
1x Elixir of Immortality
3x Darksteel Ingot

Hunger, while good, would suck here, since his "smallish" creatures would be lying around due to your own creatures. Hence, it's these he'd sacrifice first... and it's not the small creatures that are a problem for this deck, it's the bigger creatures that can't be handled by your own 2/2 creatures.

It's either Flesh to dust, or Assassinate.
I chose Flesh to dust simply because there are already a lot of 3 drops to play, and you'll draw more than enough to be able to afford 2 more mana for instant speed.
In your example, you're not doing much during three turns - turn 3, 4 and 5.

Basically :
Turn 3 : Cultivate (3 mana used, 0 left)
Turn 4 : Archaeomancer (4 mana used, 1 left)
Turn 5 : Cultivate (3 mana used, 3 mana left)

That's a lot of turns doing nothing but ramp - remember, this is NOT a ramp deck, you only have 2 fatties.

why aren't B/U/G decks called Urborg decks tho?

I don't know, I kind of want to build a deck that makes the "Cruel Sadist + Illusionist's Bracers + Paragon of Open Graves" combo work.

I'm fiddling around with Cruel Sadist myself right now, using Doubling Season + Illusionist's Bracers to make the most out of her. I wanted to ask why you mentioned Paragon of Open Graves, though? It doesn't apply a +1/+1 counter, so all it does is make the Cruel Sadist a base 2/2.
