First off doesnt electrolyze cost 3?
Also, how is this better then lava dart, or even fire/ice.
Yup, sorry, i copy/pasted it and it didn't copy the mana symbols :-/.
Why is this better than Fire/Ice or Lava Dart? It generates more CA than both of those cards. When there are two critters on the board, Fire/Ice gives an adantage of +1, Electrolyze gives +2, the equivalent of an Ancstral. And Lava Dart... there are times you can't or can't afford to sac one of your mountains. And Lava Dart doesn't cycle, Electrolyze does.
