My Deck Analysis: Knowledge Ascension v1.1

After finally getting to playtest my Knowledge Ascension deck, I found that I needed to make some big changes. My two biggest concerns were that 1) I had too many spells in which there were 2 in my deck, and 2) I needed a few more lands. I got mana screwed nearly every game, and I couldn't get Pyromancer Ascension off consistently. This being said, here is the new version:

Enchantments:
4x Pyromancer Ascension

Artifacts:
2x Knowledge Pool

Sorceries:
4x Preordain
4x See Beyond
4x Foresee
2x Slagstorm

Instants:
4x Turn Aside
4x Mana Leak
4x Lightning Bolt
4x Burst Lightning

Land:
9x Island
8x Mountain
4x Terramorphic Expanse
3x Halimar Depths

Sideboard:
4x Disperse
4x Negate
3x Steel Sabotage
2x Pyroclasm
2x Arc Trail

(On Tapped Out here)

With the sideboard, I have the Pyroclasm/Arc Trail combo for aggro decks with small creatures (it'd be 4x Pyroclasm if I had them), Disperse for creatureless decks or decks that rely on enchantments, and Steel Sabotage for decks relying on artifacts. Honestly, the Negates are in the sideboard because I wasn't sure what to put in there. Apparently I'm short on blue cards.

Here's to hoping for a good night at FNM.
