[Primer/Deck] Pox

[TTX]

Hi guys, I would like your advise.

I've been playing the deck for 2 years now (my favorite MTG deck ever btw)
I keep being told that BUG Delver is a favorable matchup

... but I have yet to actualy win an actual matchup against the beast.
They always have "that last abrupt decay"
to break through a Liliana of the veil an ensanring bridge or a trinisphere

How do you approach the matchup?

Here is my build for reference, I'm having good results with it at my lgs so far. (if I don't have to face a BUG deck)
I even had an opponent raged-quit once (living the dream)!
Nothing fancy here, I like my build clean and right to the point.



1 Nether Spirit
1 Nether Void
1 Ensnaring Bridge
1 Night of Souls' Betrayal
1 Trinisphere

4 Inquisition of Kozilek
4 Innocent Blood
4 Smallpox
4 Hymn to Tourach
4 Sinkhole

3 Cursed Scroll
4 Liliana of the Veil

4 Dark Ritual
4 Mishra's Factory
4 Urborg, Tomb of Yawgmoth
4 Wasteland
12 Swamp

SB: 2 Pithing Needle
SB: 3 Engineered Plague
SB: 1 Trinisphere
SB: 3 Ratchet Bomb
SB: 4 Leyline of the Void
SB: 1 Ensnaring Bridge
SB: 1 Night of Souls' Betrayal

I think playing Sensei's Top and swamp fetch lands would greatly improve Pox gameplay.
