Is Land Destruction Extinct?

[MtgPhreakin]

Counters:
4 mental misstep
4 force of will
2 force spike
2 daze
3 stifle

LD:
4 sinkhole

Removal:
3 chain of vapor

LD/removal:
4 smallpox

Kill:
4 entomb
4 bloodghast
1 nether spirit
3 tombstalker

Manabase:
4 wasteland
3 rishadan port (4 is harsh because I need 2 black mana)
2 urborg, tomb of yawgmoth!?
1 oboro, palace in the clouds (for bloodghast)
4 polluted delta
4 underground sea
2 island
2 swamp

SideBoard:
4 engineered explosives (against weenies)
4 leyline of the void (LD sucks against dredge, maybe surgical extraction for life from the loam?)
3 spell pierce (combo, enchantress)
2 llawan (merfolk, progenitus)
2 submerge (zoo)

Everything is quick and low mana cost. Sorry, I don't run Bob with Tombstalker and Force of Will (bad memories there).The deck essentially tries to counter the first play with mental misstep or "unless its controller pay 1" cards or the occasional stifle the first fetchland play Force of will is for unexpected things that need to be countered like natural order or goblin charbelcher...
You've got sinkhole, wasteland and smallpox for land kill. And then you have rishadan port to stop their remaining mana.
Chain of vapor is a good all removal in a sense because the deck will try to mana cripple the opponent and play daze or so when tarmogoyf or knight of the reliquary try to hit the board again. They won't be able to afford to sacrifice a land. The only thing I'm worried about is a bounced tombstalker I like to play entomb in turn 1 or 2 because people always expect a reanimator deck and instead I fetch a nether spirit/bloodghast/narcomoeba? Tombstalker gets out pretty fast so I run 3.

What do you think? Does it suck? Is it awesome anyways
Questions: Can this deck not be called an LD deck because all it has is smallpox (which might not be considered LD?), sinkhole and the maybe conditional wasteland? Should one splash white for vindicate, swords, stoneforge and mana tithe (my favorite card) lol?

What about this combo?

urborg
spreading algea
rishadan port

Use rishadan port to kill any land xD?

PS: Can anyone tell me how to properly post links so that if you hold your mouse over the name the picture of the card is displayed? This is my st post...
