I think e tutor boards are fairly common. Some people are more on that plan than I though. I only use it for devastating effects, plus I like having a real side board for the most part.

Here's my current list:
2 Zealous persecution
2 Disenchant
1 Sword of Feast and Famine
1 Enlightened Tutor
1 Engineered Plague
1 Engineered Explosives
2 Thalia, Guardian of Thraben
2 Rest in Peace
1 Grafdiggers Cafe
1 Perish
1 Choke

Sometimes I'll have a second perish over the cage because both are good against elves, but perish is solid versus the BUG decks
