[Deck] UW(x) Landstill

[Shawn]

2 P2E

After seeing this deck in action at the GP, and doing some minor playtesting with it, I also want to squeeze in a pair of Paths to the main. I play two in the board and always seem to board them in. I've haven't come to a solid conclusion on what to cut from my list; I don't want any less than 3 Decree, 2 Elspeth, and 3 sweepers.

7 basics seems to be >format right now

I run seven as well. Here's my manabase:

4 Flooded Strand
3 Polluted Delta
4 Tundra
1 Underground Sea
1 Swamp
3 Island
3 Plains
3 Mishra's Factory
2 Wasteland

15 blue sources and 14 white. Seven basics have been fantastic for me. After Zendikar, I plan on playing 2 Marsh Flats and 1 Delta, since white producing lands are more important against decks that attack landstill's manabase, and I only play two Counterspells so UU is less relevant. When I've been playtesting recently I've had a bunch of situations where I looked at a Delta in mine hand and said "I wish this found a basic Plains". Also, I only play B spells in the board, which is why I only have two lands that produce B. I have a total of 9 black sources, which is usually what most people run.

Has anyone tested Ravenous Trap as a Cunning Wish target? I'm really intrigued by it:

Ravenous Trap
2
Instant - Trap Uncommon
If an opponent had three or more cards put into his or her graveyard from anywhere this turn, you may pay 0 rather than pay Ravenous Trap's mana cost.
Exile all cards from target player's graveyard.

It seems better than Extirpate against Dredge and aggro loam, and it doesn't force you to fetch a land that produces B.
