I also got the same wrong first impression but it became a staple in aggressive decks back in the old Extended days (Sligh/Suicide Black/PTJunk/LLL/Ponza) and far more efficient than its predecessor: the Hammer Of Bogardan...It also helped a lot also to get rid of those white annoying creatures with protection (White Knight/Mother Of Runes/Soltari Priest, etc)My decklist is deliberately sub-optimal (I wanted an easy deck to pilot for my friends re-using the cards I have) and the Scroll spot really belongs to Price Of Progress or more burn in current metagame

I had an earlier version running 3 Mox Diamond to get a better chance of turn 1 Grim Monolith , Lightning Greaves or Chalice at 1; however I found out that the Dynamos/Voltaic Keys help a lot more to develop in the mid-gameMy deck is based in following list (just adapting to what I have available in my old card pool): http://www.mtgthesource.com/forums/showthread.php?22722-Tournament-Report-Dutch-Legacy-Championship-Top8-145
