rack and ruin vs crash

[twn_domn]

Many builds in T1 have rack and ruin in the SB.  One example would be the Gay Fish deck.  However, I have found that rack and ruin does not really generate the artifact hate I would like to happen when I side it in.  

Face it, the most dominant deck that uses artifact is workshop varients, which involves tangle wire and smokestack most of time.  Too often, I run into the siutation of holding rack and ruin in my hand, can't get to the 4 mana because of sphere of resistance.  However, crash provides a nice way to deal with the resistance problem.  Tap the mt, sac the mt, and then destory the smokestack/sphere/tangle wire or whatever artifact that you hate while resistance is in play, that's a huge plus.  

Ok, granted, crash does not provide any additional benefits if 3sphere or welder is out.  However, so is rack and ruin.  Strictly speaking in term of just these 2 cards, I believe crash's alternative casting cost is actually better than rack and ruin's X2 artifact destruction.  

Am I missing something important?  Feedback is welcomed.
