The Boonweaver combo goes as follows:

When Boonweaver enters play, find Pattern of Rebirth and attach it to him.
Sac Boonweaver to find Karmic Guide which returns Boonweaver and Pattern.
Sac Boonweaver again to find Fiend Hunter, who exiles Karmic Guide.
Sac Fiend Hunter to return Karmic Guide, who then returns Boonweaver and Pattern.
Sac Boonweaver again to find Reveillark.
Sac Karmic and then Reveillark to return both Karmic and Fiend Hunter.
Use Karmic to return Boonweaver and Fiend Hunter to exile Karmic.
Sac Boonweaver to go get anything.
Sac Fiend Hunter to return Karmic, which returns Reveillark.
Repeat
